(A) If the dropped shot put compresses the spring 0.200 m, what is the force constant k of the spring?

(B)When does the shot put have its largest speed?

(C) When if ever foes the shot put have zero speed

Answer 1

b) when it is just about to touch the spring it will have maximum velocity after which spring will compress speed of the ball will began to decrease
