A skier starts stationary at the top of a 20 m long slope and begins to descend. The
skier's acceleration is 0.2 m/s?. At the bottom of the slope the skier glides under a
frictional deceleration of 0.1 m/s?.
(1) Calculate the speed of the skier at the bottom of the slope.
(ii) Calculate how far the skier glides before coming to rest.
An athlete of mass 70 kg begins to run, and is observed to have velocity over the first 5
strides of 3.0, 4.2, 5.0, 5.6, and 6.0 m/s. For each stride calculate the net impulse delivered
due to the horizontal ground reaction force.
In a "crazy elevator ride" at the amusement park, a 300 kg "elevator car" slides vertically down a frictionless shaft and curves onto a horizontal section, descending a total height of 25 m. On the horizontal section is a friction pad designed to bring the car to rest. If the coefficient of friction between the car and the pad is μk=0.4, how long in meters does the pad need to be to stop the car?
A 40 kg skier starts from rest at a height of H = 19 m above the end of the ski-jump ramp. As the skier leaves the ramp, his velocity makes an angle of 27° with the
horizontal. Neglect the effects of air resistance and assume the ramp is frictionless.

(b) If he increased his weight by putting on a backpack, would h then be greater, less, or the same?
