4) In the diagram shown, a ball of mass 0.100 kg collides, in a perfectly inelastic collision, with a pendulum of mass 0.200 kg on a string of length 1.00 m. What is the minimum speed of the incoming ball before the collision so that the pendulum+ball swings through a complete circle? (Hint: the pendulum is a string. At the top of its swing it has a non-zero speed. Find this speed by setting the tension in the string to zero, then think about energy conservation during the swing up after the collision) {=1.00 m O 0.100 kg speed v 0.200 kg

A simple pendulum is made from a 0.59 m long string and a small ball attached to its free end. The ball is pulled to one side through a small angle and then released from rest. After the ball is released, how much time elapses before it attains its greatest speed?

A 2.15 kg pendulum bob on a string 1.50 m long, is released with a velocity of 3.75 m/s when the support string makes an angle of 37.5* with the vertical. What is the velocity of the bob at the bottom of the swing?
