Accepted Answer

A 100 g ball of putty traveling at 3.0 m/s strikes and sticks to another 100 g ball of putty at rest on a frictionless surface. The combined balls then compress a horizontal spring with a spring constant of 3.5 N/m. The other end of the spring is firmly anchored to a fixed post on the surface. How far will the spring compress?

Answer

A 100 g ball of putty traveling at 3.0 m/s strikes and bounces off another 100 g ball of putty at rest on a frictionless surface. The first ball then compresses a horizontal spring with a spring constant of 3.5 N/m. The other end of the spring is firmly anchored to a fixed post on the surface. How far will the spring compress?

Answer

A 100 g ball of putty traveling at 3.0 m/s strikes and sticks to another 100 g ball of putty at rest on a rough surface with friction. The combined balls then compress a horizontal spring with a spring constant of 3.5 N/m. The other end of the spring is firmly anchored to a fixed post on the surface. How far will the spring compress?

Answer

A 100 g ball of putty is at rest next to another 100 g ball of putty on a frictionless surface. The balls are pushed together by a horizontal spring with a spring constant of 3.5 N/m. The other end of the spring is firmly anchored to a fixed post on the surface. How far will the spring compress?
