Question

A skier starts from rest at the top of a hill that is inclined at 10.9° with
respect to the horizontal. The hillside is 220 m long, and the coefficient of
friction between snow and skis is 0.0750. At the bottom of the hill, the snow
is level and the coefficient of friction is unchanged. How far does the skier
glide along the horizontal portion of the snow before coming to rest?

A crate of mass m is initially at rest at the highest point of an inclined plane, which has a height of 4.7 m and has an angle of θ = 28° with respect to the horizontal. After it has been released, it is observed to be traveling at v = 0.85 m/s a distance d after the end of the inclined plane as shown. The coefficient of kinetic friction between the crate and the plane is μp = 0.1, and the coefficient of friction on the horizontal surface is μr = 0.2. Find the distance d, in meters.
A 2 kg box is put on the surface of an inclined plane at 27 degrees with the horizontal. The kinetic coefficient of friction is μ = 0.3. If released from rest at a height of 3 meters, how long would it take the box to reach the bottom?
A student is skateboarding down a ramp that is 6.02 m long and inclined at 22.3° with respect to the horizontal. The initial speed of the skateboarder at the top of the ramp is 4.98 m/s. Neglect friction and find the speed at the bottom of the ramp.
Three identical balls (ball 1, ball 2, and ball 3) are thrown at the same speed from the top of the same building. Ball 1 is thrown downward at 45 ° below the horizontal, ball 2 is thrown horizontally, and ball 3 is thrown upward at 45 ° above the horizontal. Which ball is going fastest just before it hits the level ground below the building (i.e., has the largest impact speed)? Assume air drag on the balls is negligible.
