A ball of mass m = 1.65 kg is released from rest at a height h = 66.0 cm above a light vertical spring of force constant k as in Figure [a] shown below. The ball strikes the top of the spring and compresses it a distance d = 7.70 cm as in Figure [b] shown below. Neglecting any energy losses during the collision, find the following. Figures a and b show a ball of mass m above a spring of force constant k that is vertically aligned such that its lower end is attached to the ground and its upper end is unattached. The bottom of the ball is a distance h above the top of the spring. The ball is touching the top of the spring, which has been compressed a distance d. (a) Find the speed of the ball just as it touches the spring. m/s (b) Find the force constant of the spring. kN/m

Question
A ball of mass
m = 1.65 kg
is released from rest at a height
h = 66.0 cm
above a light vertical spring of force constant k as in Figure [a] shown below. The ball strikes the top of the spring and compresses it a distance
d = 7.70 cm
as in Figure [b] shown below. Neglecting any energy losses during the collision, find the following.
Figures a and b show a ball of mass m above a spring of force constant k that is vertically aligned such that its lower end is attached to the ground and its upper end is unattached.
- The bottom of the ball is a distance h above the top of the spring.
- The ball is touching the top of the spring, which has been compressed a distance d.
