Sam, whose mass is 74.0 kg, takes off across level snow on his jet-powered skis. The skis have a thrust of 220.0 N and a coefficient of kinetic friction wtih the snow of 0.07. Unfortunately, the skis run out of fuel after only 11.5 seconds. What Sam's top speed (in m/s) assuming that the acceleration due to gravity is 9.80 m/s2? How far (in m) has Sam traveled when he finally coasts to a stop?

In the figure, a 3.6 kg block slides along a track from one level to a higher level after passing through an intermediate valley. The track is frictionless until the block reaches the higher level. There a frictional force stops the block in a distance d. The block's initial speed is vo = 6.8 m/s, the height difference is h = 0.99 m, and uk = 0.592. Find d. d H = 0- Number Units the tolerance is +/-5%

Computation. A block is released from rest at the top of a 47-m long frictionless ramp inclined at 34° above the horizontal. What is the block's speed at the bottom of the ramp? v= m/s Record your numerical answer below, assuming three significant figures. Remember to include a "-" if/when necessary.

A 62.0 kg skier is moving at 6.10 m/s on a frictionless, horizontal, snow-covered plateau when she encounters a rough patch 4.50 m long. The coefficient of kinetic friction between this patch and her skis is 0.300. After crossing the rough patch and returning to friction-free snow, she skis down an icy, frictionless hill 2.50 m high. ▼ Part A How fast is the skier moving when she gets to the bottom of the hill?

a) What is the speed of the basketball immediately before the collision, i.e. just before making contact with the ground? In other words, what is v,? b) What is the speed of the basketball immediately after the collision, i.e. just after the ball has decompressed? In other words, what is v;? c) Is the collision of the basketball with the ground an elastic or inelastic collision? Explain your answer and support it with calculations. d) Calculate the average force exerted by the ground on the basketball during the collision. In other words, calculate the average normal force during the collision.
