- A skier starts from rest at the top of a hill that is inclined 9.50° with respect to the horizontal. The hill slide is 1.50x102 m long and the coefficient of friction between snow and skies is 0.0800.What is the speed of the skier at the bottom of the hill?A block of ice with mass 2.00 kg slides 1.35 m down an inclined plane that slopes downward at an angle of 36.9° below the horizontal. If the block of ice starts from rest, what is its final speed? Ignore friction. ( draw free-body diagram)A sled, of mass 18.6 kg, is stationary when it starts to slide down an icy hill. The hill is 13.0 m tall. Assuming friction is minimal, what is the speed of the sled at the bottom of the hill? Give your answer in m/s to 1 decimal place.
- A rock falls from a vertical cliff that is 4.0 m tall and experiences no significant air resistance as it falls. At what speed will it's gravitational potential energy (relative to the base of the cliff) be equal to its kinetic energy in m/s?At Schlitterbahn, a 75.0 kg person rides a 12.0 m high water slide. If dissipative forces do -6.25 x 10³ J on the rider as they go from rest at the top of the ride to the bottom, then what is the speed of the rider at the bottom of the slide? Include a diagram of the situation and indicate the mechanical energy at both the top and at the bottom of the slide.A child and sled with a combined mass of 32.6 kg slide down a frictionless hill, starting at the top. The sled starts from rest and acquires a speed of 6.69 m/s by the time it reaches the bottom of the hill. What is the height (in m) of the hill? Answer: m (round to the nearest hundredth)
- A roller coaster with a mass of 725 kg starts with a speed of 22.0 m/s at the bottom of a hill. At the top of the hill the roller coaster has a speed 14.0 m/s.(see diagram below). Assuming friction is minimal, what is the height of the hill? ? Give your answer in m to 2 decimal places.A 8kg crate, starting from rest, is pulled across a floor with a constant horizontal force of 230N. For the first 13 m the floor is frictionless and for the next 14m, the coefficient of friction is 0.3. What is the final speed of the crate in m/s?An object with an initial potential energy of 40 J is dropped from rest. After a while, its potential energy is 10 J, and its kinetic energy is 5 J. Construct a possible scenario that might explain this situation.

The hill is 5.0 m high and 100 m long. If the force of friction as she rides down the hill is 20N, what is her speed at the bottom?In the figure below, a block slides along a path that is without friction until the block reaches the section of length L = 0.80 m, which begins at height h = 2.0 m on a ramp of angle = 30°. In that section, the coefficient of kinetic friction is 0.55. The block passes through point A with a speed of 8.0 m/s. If the block can reach point B (where the friction ends), what is its speed there, and if it cannot, what is its greatest height above A? m/s BA O Ꮎ
