Question

A ball of mass 3kg is tied to a rope with a length of 1.3m. If the ball is spun at a rate of 300rpm's, find the tension on the rope, the centripetal force, and the centripetal acceleration.


Please help, I have a test on it tomorrow.

Your question is most unclear. Spun about what axis?

If the ball is spinning in a horizontal plane on a pivot to which the rope is tied, about the pivot point,

Centripetalforce=tension=mv^2/r

find v from the angular velocity (rpm) and radius.
