Using the momentum of the ball to find it's original height

  1. Jan 16, 2009 #1
    A 0.150 kg ball is dropped from rest. If the magnitude of the ball's momentum is 0.780 kg·m/s just before it lands on the ground, from what height was it dropped?

    What have you tried? What equations do you think you might need? You must show some effort in order to get help.

    i used kg m/s / kg

    .78/.15=5.2

    m/s /g

    5.2/9.8= .53

    1/2 g (m/s /g)^2=m

    1/2x9.8x.53^2=1.38

    it said that i got it right
