Power Question !!Need Help 1. The problem statement, all variables and given/known data A particle of mass 'm' is moving in a Circular path of constant radius 'r' such that it's centripetal acceleration is given by ac= k2rt2 where k is constant. The power delivered to the particle by the force acting on it is :- A) 2(pi)mk2r2t B) mk2r2t C) (mk4r2t5)/3 D) zero 2. Relevant equations 3. The attempt at a solution Centripetal force will be f=mac so f=mk2rt2. Now, Centripetal acceleration = v2/r. so v= krt now, power = force*distance/time for which work is done (mk2rt2*vt)/t from this i am getting power as mk3r2t3.
