An 8-kg ball rolling at 2m/s bumps into a pillow and stops in 0.5s (a) Show that the force exerted by the pillow is 32N. (b) How much force does the ball exert on the pillow?

  • physical science -

    (a) Initial momentum = impulse
    8 kg * 2 m/s = Force * 0.5 s
    Force = __ Newtons

    (b) Use Newton's third law
    action = reaction
    (This refers to forces objects exert on each other)
