Help! Physics Momentum/Impulse problem!

  1. Feb 10, 2012 #1
    If a baseball were flying towards an outfielder with a momentum of 900 kg m/s. What impulse would the outfielder need to apply to bring the ball to a stop? AND If the maximum force the dude can exert is 100N for what length of time will he have to exert this force?

    This sounds like a homework question.
    Please post it in the homework forums and they can help you there.

    I think there is something wrong with your number. I don't know the mass of a baseball but I would guess about 0.2 to 0.3 kg.
    To have a momentum of 900 kg m/s means a velocity of 3000 to 4500 m/s and that does not sound reasonable
