Question

A linear (ie: it obeys Hooke’s Law) spring is placed vertically on the ground. A 200 g block is released from a height of 50 cm above the top of the spring and dropped onto it. The block compresses the spring 13 cm before coming to rest.

a) Determine the stiffness constant k of the spring. (Do I include the height here?)

b) Determine the equilibrium position (the place at which it can sit at rest – and remain there) of the block on the spring. How compressed will the spring be at this position?

c) Determine the speed of the block as it passes through the equilibrium position on its way back up
