ball of mass m = 1.70 kg is released from rest at a height h = 54.0 cm above a light vertical spring of force constant k. The ball strikes the top of the spring and compresses it a distance d = 8.80 cm Neglecting any energy losses during the collision, find the following.


a) Find the speed of the ball just as it touches the spring.
m/s

(b) Find the force constant of the spring.
N/m
