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 pendulum is moving in a circular motion with a constant speed of 10m/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.
