A skier accelerates to a speed of 56 m/s over a distance of 151 m. Determine the acceleration (assume uniform) of the skier.
Show your work for acceleration.
Include Units
The acceleration of the skier over the distance traveled is 10.38 m/s²
The given parameters;
Initial velocity of the skier, u = 56 m/sDistance covered by the skier, s = 151 mAcceleration is defined as the change in velocity per change in time of motion.
The magnitude of the acceleration of the skier is calculated as follows;
[tex]v^2 =u^2 - 2as\\\\[/tex]
where;
v is the final velocity at the end of 151 m = 0
[tex]0 = 56^2 -(2\times 151)a\\\\302a = 3136\\\\a = \frac{3136}{302} \\\\a = 10.38 \ m/s^2[/tex]
Thus, the acceleration of the skier over the distance traveled is 10.38 m/s²

A 5.0 kg cannonball is fired horizontally at 68 m/s from a 15-m-high cliff. A strong tailwind exerts a constant 12 N horizontal force in the direction the cannonball is traveling. What is the extra distance (d)?
Answer:
3.7 m
Explanation:
ASSUMING this means extra distance beyond where the cannonball would land WITHOUT the wind assistance but in general ignoring air resistance. Hmmmmmm...tricky
The ball drops from vertical rest to ASSUMED horizontal ground 15 m below in a time of
t = √ (2h/g) = √(2(15)/9.8) = 1.75 s
Without the tail wind, the ball travels horizontally
d = vt = 68(1.75) = 119 m
The tailwind exerts a constant acceleration on the ball of
a = F/m = 12/5.0 = 2.4 m/s²
The average horizontal velocity during the flight is
v(avg) = (68 + (68 + 2.4(1.75)) / 2 = 70.1 m/s
so the distance with tailwind is
d = v(avg)t = 70.1(1.75) = 122.675 m
The extra distance is 122.675 - 119 = 3.675 = 3.7 m

What happens to a moving object if NO unbalanced force acts upon it?
It eventually slows down and comes to a stop.
It speeds up in the direction of motion.
It will eventually change direction.
It continues to move at the same speed.
Answer:Newton's first law of motion indicates that an objects motion or lack of motion will stay the same unless acted upon by an unbalanced force.

Some thermal mugs have layers of materials to keep drinks hot for as long as possible. Which combination of layers would work best for this purpose? A. Inner core of steel, no air gap, outer layer of glass B. Inner core of steel, air gap, outer layer of plastic C. inner core of steel no air gap outer layer of glass D inner core of steel no air gap outer layer of plastic
DONT ANSWER IF U DONT KNOW DO NOT GUESS THIS IS FOR A GRADE
The best combination of layers that would work best for this purpose is an inner core of steel, no air gap, and an outer layer of glass. Option A is correct.
Thermal mugs have the ability to maintain the internal body temperature and heat of their container. For the heat to be maintained for an extended period of time. The internal core must be lined with steel because it radiates less heat compared to the glass. The steel also has high conductivity and lesser specific heat to keep drinks hot for a long period of time.
Therefore, we can conclude that for thermal mugs to keep drinks hot for as long as possible, the inner core must be lined with steel, no air gap, and contain an outer layer of glass.

When the sun heats up the suface of the water, the water
Answer:
In the water cycle, evaporation occurs when sunlight warms the surface of the water. The heat from the sun makes the water molecules move faster and faster, until they move so fast they escape as a gas. Once evaporated, a molecule of water vapor spends about ten days in the air.

Explanation:
Okay, so this is going to sound crazy but bare with me. Mar's atmosphere is thin. There is little to no gravitational pull for the atmosphere to stay. Also, no, humans will not be able to live on Mars because the atmosphere, quite literally, contains 1% oxygen. Hopefully this helps! Earth's is thick because of the gravitational pull and gases in Earth's surface.

A canoe is designed to have very little drag when it moves along its length. Riley, mass 62 kg, sits in a 21 kg canoe in the middle of a lake. She dives into the water off the front of the canoe, along the axis of the canoe. She dives forward at 1.7 m/s relative to the boat.
1) Just after her leap, how fast is she moving relative to the water?
2) Just after her leap, how fast is the canoe moving relative to the water?
(1) Riley velocity relative to the water after she jumps is 1.7 m/s.
(2) The velocity of the canoe relative to the water is 5.02 m/s.
The given parameters;
mass of Riley, m₁ = 62 kgmass of canoe, m₂ = 21 kg velocity of the Riley after jumping, v₁ = 1.7 m/s(1) Since the lake is still, her velocity relative to the water after she jumps is 1.7 m/s.
(2) Apply the principle of conservation of linear momentum;
m₁v₁ = m₂v₂
62 x 1.7 = 21v₂
105.4 = 21v₂
[tex]v_2 = \frac{105.4}{21} \\\\v_2 = 5.02 \ m/s[/tex]
Thus, after her leap, the velocity of the canoe relative to the water is 5.02 m/s.

Jake lifted a 10-kg bell by a distance of 0.50 meters in 0.50 seconds. How much power did Jake use?
Answer:
10 watts
Explanation:
first calculate work.
Work =force×distance cos thita
10Kg×0.50M cos 0= 5joules
Therefore, Power=Work÷ Time
Therefore, 5joules÷0.50s=10 watts.
