An object moves in a horizontal circle at constant speed v (in units of m/s). It takes the object T seconds to complete one revolution. a. Derive an expression that gives the radial acceleration of the ball in terms of v and T, but not r. b. If the speed doubles, by what factor must the period T change if arad is to remain unchanged?
