Find the velocity of the block in m/sec at C just before striking the spring in the above figure.  Assume m=1 Kg, R=[R] m, d=[d] m, and g=9.81 m/sec 2.

The block of mass m shown in the figure is released from rest at A and slides down the smooth circular surface of radius R to B and continues on the flat surface with coefficient of friction µ=0.2 until it strikes the linear spring k at C and compresses  the spring by x.  Answer the next 2  Questions (6-7) about this block at different points along its path. Enter your numerical answers for Questions 6 and 7 to 2 decimal places in the boxes provided.

A man weighing 180 lb  dives from a stationary boat weighing 120 lb. The (absolute) velocity of the man after separation is vman=[u]i+[v]j ft/sec. What is the horizontal (x-component) velocity of the boat in ft/sec after separation assuming the man and the boat are initially at rest?

For a system of particles

Regardless of your answer in Question 6 suppose that the 1 Kg block strikes the linear spring k=[k]0 N/m (initially undeformed) with a velocity of v=[v] m/sec. Find the maximum compression of the spring in meters produced by the moving block just before the block rebounds. Ignore friction.

The angular momentum of a system of particles about a fixed point O is constant if and only if
