A vertical spring, whose spring stiffness constant is 1100 N/m, is attached to a table and is compressed down 0.160 m.
(a) What upward speed can it give to a 0.600 kg ball when released?
m/s
(b) How high above its original position (spring compressed) will the ball fly?
m
For A I got 6.6m/s which is correct and for b I got 2.23 but it is wrong.
