The potential energy of a particle of mass 5 kg moving in x-y plane is given by u = (7x + 24y) j, where x and y being in meters. If particle starts from rest from origin, then speed of particle at t = 2 sec, is 1 is 1 The potential energy of a particle of mass 5 kg moving in x-y plane is given by u = (7x + 24y) j then speed of particle at t = 2 sec where x and y being in meters.
