Created for Albert.io. All rights reserved 2016.

A ball is tied to a string and swung in a horizontal circular path at constant speed. The tension force acting on the ball is $20\ \text{N}$, and the circumference of the circular path is $1.5\ \text{meters}$.

How much work does the tension force do on the ball during one half-cycle of its motion?

A

$0\ \text{J}$

B

$5\ \text{J}$

C

$20\ \text{J}$

D

$80\ \text{J}$
