Question
a vertical spring whose spring constant is 850 n/m stands on a table and is compressed 0.400m. what speed can it give to a .300kg ball when released?
Answers

(u)potential energy stored in the spring=kx^2/2
(k.e)kinetic energy of the ball when released=1/2mv^2
u=k.e
kx^2/2=1/2mv^2
put all the known values
v=21.291625896895082665426993569307
