1. A simple pendulum acts as a conical pendulum when the mass moves in a horizontal circle. (a) What force keeps it moving in a circle? Please explain. (b) Assume the pendulum is moving in a circular motion with a constant speed of 10 m/s. Calculate the angle formed between the pendulum with the vertical direction if its mass is 2.0 kg, and it describes a circle with radius of around 10 cm. (c) Compute the work done by centripetal force.

(a) The force responsible for any rotational motion is the centripetal force. In this case it is…

What formula would I need to use to solve this problem: The rope of a swing is 2.90 m long. Calculate the angle from the vertical at which a 84.0 kg man must begin to swing in order to have the same KE at the bottom as a 1440 kg car moving at 1.41 m/s (3.15 mph). The decrease in gravitational PE is converted into KE as the man falls. This decrease in gravitational PE depends on the change in height.
