A 20-kg object is attached to one end of a horizontal, Ask an Expert

Academics

A 2.0-kg object is attached to one end of a horizontal spring that has a negligible mass and a spring constant of 250 N/m. The other end of the spring is fixed to a wall. The spring is compressed by 15 cm from its equilibrium position and released from rest.

1. What is the speed when the object is 7.5 cm from equilibrium?

2. What is the speed when the object is at the equilibrium position?

3. What is the speed of the object when it is 13.0 cm from equilibrium?
