Given :
A ball that has a mass of 0.25 kg spins in a circle at the end of a 1.6 m rope.
The ball moves at a tangential speed of 12.2 m/s.
To Find :
The centripetal force acting on the ball.
Solution :
We know, centripetal force is given by :
[tex]F = \dfrac{mv^2}{r}\\\\F = \dfrac{0.25\times 12.2^2}{1.6}\\\\F = 23.26 \ N[/tex]
Therefore, the centripetal force acting on the ball is 23.26 N.
