potential energy stored in a compressed spring is 3 J.
the spring constant is k=1500 N/m
(a) calculate the magnitude of the force in this spring
(b) the above spring used to eject a 0.1 kg projectile from aspring gun at rest.
what is the exit speed of the projectile? ignore the mass of thespring of the gun and all forces other than the spring force
(c)if the projectile is ejected from ground level verticallyupward, what is the maximum height will it reach?
