Problem 6-53 parts (a), (b), and (c) Centripetal force - B

A conical pendulum consists of a mass (the bob) on the end of a string. As the bob travels in a horizontal circle at constant speed, the string traces out a cone. For the pendulum shown, mass \(m = 1.95\; kg\), length \(l = 1.03\; m\), and angle \(\theta = 36.9^\circ\).

(a) Draw a free body diagram for the bob at the instant shown.
(b) What force constitutes the centripetal force?
(c) Determine the speed of the bob.

Diagram of conical pendulum.

No. A string cannot push; it can only pull.
