If a basketball player jumps and lands on the ground after 3.2 seconds with a final velocity of −5.5 m/s, what is the player’s initial velocity? Assume (a=−9.8 m/s2)
Show some work
The initial velocity of the player, given it landed on the ground after 3.2 s is 15.68 m/s
How to determine the timeWe'll beging by obataining the time taken for the player to reach the maximum height. This can be obtannnned as follow:
Time for the entire trip (T) = 3.2 sTime to reach maximum height (t) = ?T = 2t
3.2 = 2t
Divide both sides by 2
t = 3.2 / 2
t = 1.6 s
How to determine the initial velocity of the playerThe initial velocity of the player can be obtained as follow:
Time to reach maximum height (t) = 1.6 sAcceleration due to gravity (g) = -9.8 m/s²Final velocity (v) = 0 (at maximum height)Initial velocity (u) = ?v = u + gt
0 = u + (-9.8 × 1.6)
0 = u - 15.68
Collect like terms
u = 0 + 15.68
u = 15.68 m/s
Thus, we can conclude that the initial velocity of the player is 15.68 m/s

Infrared radiation has wavelengths ranging from about 800 nm to 1 mm. What is the corresponding frequency of radiation of a wavelength of 970 nm?.
By using electromagnetic waves, the frequency of radiation is 3.09 x 10¹⁴ Hz.
We need to know about electromagnetic waves to solve this problem. Electromagnetic waves can propagate without media. The speed of electromagnetic in vacuum media is equal to the speed of light. Hence, the wavelength and frequency can be determined as
c = λ . f
where c is the speed of light (3 x 10⁸ m/s), λ is wavelength and f is frequency.
From the question above, we know that
λ = 970 nm = 970 x 10¯⁹ m
By substituting the given parameter, we can calculate the frequency of radiation
c = λ . f
f = c / λ
f = 3 x 10⁸ / 970 x 10¯⁹
f = 3.09 x 10¹⁴ Hz

22 days from now the star Betelgeuse, of the constellation Orion will rise at 11:40 pm
Given that,
Time at which the star rises today = 1:12 am
The stars rise about 4 minutes earlier each night
Minutes earlier it will rise 22 days from now = 4 * 22 = 88 minutes
= 1 Hr 28 Min
The star should rise 1 Hr 28 Min earlier from 1:12 am which is 11:44 pm
But since the time from today to 22 days from now crosses the 12 am mark, the star will be seen twice on the same day. This means that the star seen on 11:44 pm is actually on the 21st day. On 22nd day the star is seen 4 minutes earlier than 11 pm which is 11:40 pm.
We rotate one degree every 4 minutes. We revolve a little more than 1 degree every day around the sun (365 days divided by 360 degrees is 1.014 degrees). So everyday we get to see the star 4 minutes early which is 1 degree.

By using uniform motion, the distance traveled by the car is 216 m.
We need to know about the uniform motion to solve this problem. The uniform motion is an object's motion under acceleration. It should follow the rule
vt = vo + a . t
vt² = vo² + 2a . s
s = vo . t + 1/2 . a . t²
where vt is final velocity, vo is initial velocity, a is acceleration, t is time and s is displacement.
From the question above, we know that
vo = 15 m/s
vt = 21 m/s
t = 12 s
Find the acceleration
vt = vo + a . t
21 = 15 + a . 12
12a = 6
a = 0.5 m/s²
By using the third equation, we can calculate the distance
s = vo . t + 1/2 . a . t²

a. are time-independent
b. are perfectly correlated
c. are independent
d. are perfectly anticorrelated
The correct option is D.
The Kinetic Energy and The Potential Energy are perfectly anti-correlated.
Kinetic energy and potential energy are two types of energy that are frequently found in mechanical systems and are referred to as mechanical energy in physics. The idea of mechanical energy conservation is based on an even more general principle known as the law of conservation of energy; the main distinction is that in mechanical energy conservation, all the system's energy is either in the form of kinetic energy, potential energy, or both. A restoring force in a harmonic oscillator works in the direction of an equilibrium point. Simple harmonic motion, which we refer to as repeating the motion, is produced by the force. The system's mechanical energy, which includes both potential and kinetic energy, is ideally constant. In actuality, the energy is preserved by allowing one quantity to grow when the other shrinks, and vice versa. An anti-correlation is a term that describes a negative correlation.
To summarize the kinetic energy and potential energy in a harmonic oscillator are perfectly anti-correlated. The correct option is D.

An object is launched from the base of an incline, which is at an angle of 30° If the launch angle is 60° from the horizontal and launch speed is 10m/s. What is the total flight time ?
Answer:
4.6 s, because that is the time for the object to reach the top of the incline.
Explanation:
that at the top of the incline, the horizontal velocity will be equal to the launch velocity, because there is no longer any force acting on the object in the horizontal direction. The only force acting on the object is gravity, which is acting in the vertical direction. So the only velocity that will be changing is the vertical velocity. The vertical velocity will be changing because of the force of gravity, which is 9.8 m/s2. The equation for the vertical velocity is: vf = vi + a*t, where vf is the final velocity, vi is the initial velocity, a is the acceleration and t is the time. The final velocity in this case is 0 m/s, because the object has reached the top of the incline and is no longer moving in the vertical direction. The initial velocity is 10 m/s, because that is the launch velocity. The acceleration is 9.8 m/s2, because that is the force of gravity. So when you plug all of those values into the equation, you get: 0 = 10 + 9.8*t and you solve for t and you get t = 4.6 s.
Someone standing at the edge of a cliff throws one ball straight up and another ball straight down at the same initial speed. Neglecting air resistance, which ball has the greatest final velocity upon reaching the ground?.
Both balls have the same velocity upon reaching the ground.
Each ball is given some kinetic energy at the edge of the cliff that takes one upwards and the other down.Since the launching height is the same for both balls each one possesses some potential energy measured relative to the ground down there.Since the air resistance is neglected there would be no resistive forces acting upon each ball that could draw away some of the energy each ball has and therefore, the mechanical energy of each ball is conserved throughout the flight.So, if one writes the energy equation from the edge of the cliff to the ground, it would yield the following result.[tex]\begin{aligned}\\\small K.E +P.E &=\small K.E_1 +P.E_1\\\\\small \frac{mv^2}{2}+mgh&=\small \frac{mV^2}{2}+0\\\\\small V&=\small \sqrt{v^2+2gh}\end{aligned}[/tex]
The magnitude of the final velocity does not depend on the mass of the ball.Therefore, both balls would have the same velocity at the ground as they are given the same initial speed at the same initial height.#SPJ4

Acceleration is the rate of change of velocity. An object can have a greater speed but with zero acceleration if the velocity is constant.
For example, Consider a driver A driving his car at a constant speed of 60 Kmph. and crosses another driver B. Consider driver B at rest the moment the driver A crosses him. But the driver B drives faster than the driver A and catches up with driver A even though the driver A was driving at 60 Kmph when the driver B just started driving from 0 Kmph.

Absorption or emission lines for hydrogen occur when electrons change energy levels. These correspond to specific wavelengths and can be calculated by using:
1/λ = RH (1/n^2f - 1/n^2)

For the 92.97 absorption, initial=1, solve for final
1/92.92×10^-9=R(1/1^2 - 1/final^2)
(1/92.97×10^-9)*(1/1.096775×10^7)=1/1^2 - 1/final^2
