**Summary::**A block of mass m is dropped onto the top of a vertical spring whose force constant is k. If the block is released from a height h above the top of the spring,

a) what is the maximum energy of the block?

b) What is the maximum compression of the spring?

c) At what compression is the block's kinetic energy half its maximum value?

A block of mass m is dropped onto the top of a vertical spring whose force constant is k. If the block is released from a height h above the top of the spring,

a) what is the maximum energy of the block?

b) What is the maximum compression of the spring?

c) At what compression is the block's kinetic energy half its maximum value?Anybody who can solve these 3 parts of the question, although I have a solution but I am confused whether its right or wrong so need your directions...

For part a) either max. energy would be

**mgh**or

**mg(h+x)**

For part b) either expression would be

**mgh=(1/2)kx^2**or

**mg(h+x)=(1/2)kx^2**

For part c) I am stucked how to solve this part, kindly help me out to solve...
