3. Work and Energy

A block of mass 0.50 kg is placed on top of a spring with negligible mass and force constant 5,000 N/m. Initially, the spring is compressed by 0.100 m. After the block is released from rest, it travels vertically upward and leaves the spring.

a) What is the speed of the block when it leaves the spring?

b) What maximum height does the block reach?

c) What is the velocity of the block half-way to the maximum height?
