What centripetal force are you imparting to ball via string

Reference no: EM13562873

Imagine that you swing about your head a ball attached to theend of a string. The ball moves at a constant speed in a horizontal circle.

(a) Can the string be exactly horizontal? Why?

(b) If themass of the ball is 0.240 kg the radius of the circle is1.70 m, and it takes 1.20 s for the ball to make onerevolution, what is the ball's tangential speed?
