A ball mass m 250 g on the end of an ideal string is, Ask an Expert

Academics

A ball (mass m = 250 g) on the end of an ideal string is moving in circular motion as a conical pendulum as in the figure in the previous problem. The length L of the string is 1.8 m and the angle with the vertical is 37^o .

(a) What is the magnitude of the torque (N m) exerted on the ball about the center of the circle of motion?

(b) What is the direction of the torque exerted on the ball about the center of the circle of motion?

(d) What is the direction of the angular momentum of the ball about the center of the circle of motion?
