at a ball game consider a baseball of mass m=0.15 that falls directly downward at a speed v=40m/s into the hands of a fan. what impulseft must be supplied to bring the ball to rest? if the ball is stopped in 0.3s, what is the average force of the ball on the catchers hand?

  • physics - ,

    Impulse = change of momentum
    = m(v0-v1)
    Average force = change of momentum / time
    = m(v0-v1)/0.3 N (assuming m=0.15 kg)
