The following questions will you learn to apply the impulse-momentum theorem to the cases of constant and varying force acting along the direction of motion. first, let us consider a particle of mass m moving along the x axis. the net force f is acting on the particle along the x axis. f is a constant force. part a the particle starts from rest at t=0. what is the magnitude p of the momentum of the particle at time t? assume that t> 0. express your answer in terms of any or all of m, f, and t.
