It takes a force of 80.0 n to compress the spring of a toy popgun 0.200m to "load" a 0.180-kg ball. with what speed will the ball leave the gun?

v = 9.43 m/s

Explanation:

According to Hooke's law;

F = kx ------------- eqn 1

where F = spring force = 80 N

k = spring constant = ?

x = spring stretch = 0.200 m

substitute for F and x to find k

80 = 0.2k
