A(n) 96.1 g ball is dropped from a height of 59.1 cm above a spring of negligible mass.The ball compresses the spring to a maximum displacement of 4.75403 cm.

The acceleration of gravity is 9.8 m/s^2.

Calculate the spring force constant k.
Answer in units of N/

1 answer

total vertical fall of ball = .591 + .048 or
.639 meters
loss of potential energy by ball = .0961 * 9.81 * .639 = .602 Joules

so
(1/2) k (.04754)^2 = .602
