Aball 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.

For this case what we must do is calculate the centripetal force of the object.

By definition, the centripetal force is given by:

Where,

v: tangential speed

r: radius of the circular path

m: mass of the object

Substituting values we have:

The centripetal force of the ball is given by:

it may be wrong but i think its a
