- A 108 kg man is skiing across level ground at a speed of 9.5 m/s when he comes to the small slope 1.2 m higher than ground level shown in the following figure. -8.0 m- f1.2 m (a) If the skier coasts up the hill, what is his speed (in m/s) when he reaches the top plateau? Assume friction between the snow and skis is negligible. 8.16 m/s (b) What is his speed (in m/s) when he reaches the upper level if a 75 N frictional force acts on the skis? 6.31 X m/sIn 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 ᎾA mass of 10.0 kg is attached to a spring on a frictionless horizontal surface.

- During a rockslide, a 620 kg rock slides from rest down a hillside that is 710 m along the slope and 240 m high. The coefficient of kinetic friction between the rock and the hill surface is 0.28.

(d) What is its speed then?Blocks 1 and 2, with masses m₁ and m2, are placed on a frictionless, horizontal table with an ideal spring between then. The blocks are moved together, compressing the spring until it stores 87 J of elastic potential energy. When released from rest, the blocks move in opposite directions. Find the maximum speed of block 1 if m₁ = 7.63 kg and m2 = 4.18 kg. m/s V =In the figure, a 4.2 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 = 6.3 m/s, the height difference is h = 0.96 m, and Hk = 0.612. Find d. H = 0- Number Units
