A vertical spring (ignore its mass), whose spring stiffness constant is 1000 N/m, is attached to a table and is compressed down 0.130 m.

(a) What upward speed can it give to a 0.200 kg ball when released?

m/s

(b) How high above its original position (spring compressed) will the ball fly?

m

Energy in compressed spring: 1/2 k .13^2

then, KEreleased=energycompressed spring, from that , find vi

how high? Mgh=1/2 k .13^2

on a.) it should be 1/2mV^2=1/2kx^2, however whenever I do this problem on my homework I get it wrong. Im not sure why.
