A remote-controlled toy car of mass 2.2 kg starts from rest at the origin at t = 0 and moves in the positive direction of an x axis. The net force on the car as a function of time is given by the figure. (a) What is the time rate of change of the momentum of the car at t = 3.0 s? (b) What is the momentum of the car at t = 3.0 s?
at t= 3.0 s for part a the force value is 4 N which is also similar for part b in order to calculate the momentum please give me your answers with units.
i have known the answer in part a which is 4N but in part b.. ive done substituting those values in the formula of impulse then i get 1.3333... so on is it right?? please help
