Question

The next three problems pertain to the same situation. An 1 kg rock is traveling to the right with a speed of vrock = 20 m/s when it hits and embeds itself in a 9 kg lump of clay that initially sits at rest on a horizontal, frictionless surface. The clay + rock subsequently travels up a frictionless ramp which is inclined at an angle of 30 degrees with the horizontal. Note that sin 30degree = 1/2 and cos 30degree = root 3/2 Use g=10 m/s2 What is the speed of clay+rock immediately after the collision? 0.5 m/s 1.0 m/s 2.0 m/s 2.2 m/s What is the maximum length D that the clay+rock can reach up the slope? (Note that I am asking for the length along the slope, not the vertical height!) 0.1 m 0.2 m 0.3 m 0.4 m 0.5 m What is the average force exerted by the clay on the stone during the collision? 10 N 18 N 200 N there is not enough information given to figure this out

Explanation / Answer

1m/s 0.4m 18N
