Question

A person takes a ball of mass 0.0600 kg, attaches it to a piece of string, and whirls it around in a horizontal circle. The radius of the circle is 0.300 m and the object moves with a constant tangential speed of 2.00 m/s. Calculate the tension in the string

Answer 1

Mass of the ball = m = 0.06 kg

Radius of the circle = R = 0.3 m

Tangential speed of the object = V = 2 m/s

Tension in the string = T

Tension in the string provides the ball with the required centripetal force for the circular motion.

T = 0.8 N

Tension in the string = 0.8 N
