The figure to the right shows a pool slide of length 5.50 m. The end point of the slide is at 30.0 cm above the water level on the pool. During a summer vacation, an initially at rest 34.5 kg child slides from the top and splashes into the pool water at a speed of 8.00 m/s. While sliding, the child encounters a constant friction of 45.0 N. (a) What is the speed of the child at the end of the slide? (b) At what height above the water leyel should the pool slide start? h 1 30.0 cm 5.50 m

The drawing shows two boxes resting on frictionless ramps. One box is relatively light and sits on a steep ramp. The other box is heavier and rests on a ramp that is less steep. The boxes are released from rest at A and allowed to slide down the ramps. The two boxes have masses of 8 and 33 kg. If A and B are 4.5 and 0.5 m, respectively, above the ground, determine the speed of (a) the lighter box and (b) the heavier box when each reaches B.

A block slides along a track with an initial velocity vo = 7.0 m/s from one level to a higher level after passing through an intermediate valley. The difference h from the initial position to the elevated track is 0.89 m. The track is frictionless until reaches the top. There (at the top), a frictional force stops the block in a distance d. The coefficient of kinetic friction between the block and the surface is 0.60. Find the distance d.
In February 1955, a paratrooper fell 360 m from an airplane without being able to open his chute but happened to land in snow, suffering only minor injuries. Assume that his speed at impact was 52 m/s (terminal speed), that his mass (including gear) was 80 kg, and that the force on him from the snow was at the survivable limit of 1.2 x 105 N. (a) What is the minimum depth of snow that would have stopped him safely? m (b) What is the magnitude of the impulse on him from the snow? kg-m/s
A 13.0kg stone slides down an icy, essentially frictionless, hill that is shown in the figure. At the top of the hill, the stone is moving at 1.75m/s down the hill. While the hill is frictionless, the stone experiences friction along the level, rough ground (beyond the base of the hill) all the way to a wall. The coefficients of static and kinetic friction are 0.800 and 0.300 respectively. The stone slides along the ground for 9.15m before making contact with a long spring, which has a spring constant of 25.0N/m. (“Long” in this case means that the spring is sufficiently long to stop the stone before it hits the wall.) Will the stone move again after it has been stopped by the spring?

Small ice cubes, each of mass 7.15 g, slide down a frictionless track in a steady stream, as shown in the figure below. Starting from rest, each cube moves down through a net vertical distance of h = 1.50 m and leaves the bottom end of the track at an angle of 40.0° above the horizontal. At the highest point of its subsequent trajectory, the cube strikes a vertical wall and rebounds with half the speed it had upon impact. If 25 cubes strike the wall per second, what average force is exerted upon the wall? N ---direction--- 1.50 m 40.0⁰
