Question

A ball, P is at point A at a height 2 m above the ground as shown in the image. The ball's mass is 3 kg.

a) What is P:s potential enery above the ground? Use g=9.82 m/s^2

The ball is let go without speed from point A and slides down the slippery circular surface AB.

b) What is the P:s kinetic energy at point B?

c) What is P:s velocity at point B?

Immediatly after point B, the ball, P collides with a box, Q and the objects stick together. The box, Q:s mass is 6 kg

d) What is the velocity of the two bodies stuck together?

e) How far along the rugged surface BC does the two bodies stuck together get before they stop if the frictional force is 5N?
