a 2-kg ball is supended from a spring. when disturbed in a vertical direction, the ball moves up and down in simple harmonic motion with a period of 0.25s.
a. what is the upward force exerted on the ball by the spring when the ball is at the midpoint of its up-and-down path?
b. how much did the spring stretch when the ball was first attached to its end (before the oscillatory motion that started)?
