Question

A 0.800-kg ball is tied to the end of a string of length 1.68m and swung in a vertical circle.

Part A

During one complete circle, starting anywhere, calculate the total work done on the ball by the tension in the string.

Part B

During one complete circle, starting anywhere, calculate the total work done on the ball by gravity.

Part C

Repeat part (a) for motion along the semicircle from the lowest to the highest point on the path.

Part D

Repeat part (b) for motion along the semicircle from the lowest to the highest point on the path.

Explanation / Answer

A) Wt = 0

B)Wg = m*g*2r = (0.8*9.8*2*1.68) = 26.3424 J

C) Wt = 0

D) Wg = m*g*r = 13.1712 J
