The linear momentum 'p' of a moving body in one dimensional frame varies with time as p = x + yt2, where x and y are position constants.The rate of change of momentum is the force that acts on the body. In such a case the force is :
proportional to t2
proportional to t
inversely proportional to t2
inversely proportional to t
