Problem
For an object moving in uniform circular motion, the magnitude of the centripetal acceleration is given by ac=v2/r, where v is the speed of the object, and r is the radius of the circle. The "jerk" is the rate of change of acceleration. For uniform circular motion, the magnitude of the jerk is given by:
a. zero b. v2/r c. v2r d. v3/r e. v3/r2
