Question

A plastic ball is tied to 1 end of a long string and is swung in a horizontal circle. If it takes to complete 1 circle, what is the acceleration of the ball

Answer 1

Step-by-step explanation:

Assuming the ball is swung with a constant velocity V and radius of circle R. Therefore, The tangential acceleration of the ball would be zero.

Considering the centripetal acceleration to be a_c . we get,

`a_c= (V^2)/(R)`
