A girl whirls a stone attached to a string 1.0m long in a circle with uniform speed. The ston completes one revolution in 0.5s.
(a) what is the speed of the stone?
(b) what are the centripetal and tangential accelerations of the stone?
(c) calculate the force provided by the rope to maintain the circular motion of the stone if the mass of the stone is 30.0g.
