Homework Help: Momentum question

  1. May 12, 2004 #1
    A 1.00 kg steel ball 4.00 m above the floor is released, falls, strikes the floor, and rises to a maximum height of 2.50 m. What is the momentum transferred from the ball to the floor in the collision?

    Ok the momentum down before the collision is around -8.85 kg m/s, up after the collision is about 7.00 kg m/s so shouldn't the amount of momentum transferred to the flour be around 15.9 kg m/s in the downward direction?

    The book gives an answer of 1.85 kg m/s down transfered. It doesn't seem right to me. Help me out here.

    Thanks

    Your answer seems correct to me. The book is wrong.
