A 0.103 kg ball is moving 11.9 m/s when it runs into a spring of spring constant 66.9 N/M . How far does the spring compress in bringing the ball to a stop?

Question

Please help quickly thank u

Answer 1

the kinetic energy of the ball is the energy that compresses the spring

1/2 m v^2 = 1/2 k x^2

.103 * 11.9^2 = 66.9 * x^2
