A 1.0 kg object is attached to one end of a 1.25 m long string. The other end of the string is fixed. The object is released from rest when the string is horizontal falls to a vertical 90-degree angle.
- What is the speed of the object as the lowest point along the path (when the string is vertical)?
- What is the value of the tension in the string at the lowest point?
- What is the work done by the tension on the object as the string goes from the horizontal position to the vertical position?

A 1.9-kg ball is attached to the end of a 2.6-m string to form a pendulum. This pendulum is released from rest with a string horizontal. At the lowest point in its swing when it is moving horizontally, the ball collides elastically with a 2.5-kg block initially at rest on a horizontal frictionless surface. What is the speed of the block just after the collision? Show all the important physics steps.
