From the question we are told that:
Velocity 
Force of friction f = 0
Angle 
Generally the equation for Radius of curvature is mathematically given by



Work is done when a force is applied to an object moves that object. the work is calculated by multiplying the force by the amount of movement of an object
A. To find work we need to know F and S; to find power we need to know F and V
