a man is on the ground level on a compressed spring. the man has a mass of 60kg and the spring is compressed 0.5 and has a spring constant of 500nm.
a)what is the maximum height will the man achieve and the spring decompresses?
B)find the velocity right after he leaves the spring.

ap physics 
drwls,
a) Solve (1/2)k X^2 = M g H for the maximum height, H
b) Solve (1/2) k X^2 = (1/2) M V^2
for the initial velocity, V
X is the initial compression, which I assume is in meters. (You should have said what the dimensions are)
k is the spring constant and M is the mass.
