The classic momentum transfer between balls question

  1. Mar 18, 2012 #1
    1. The problem statement, all variables and given/known data

    A 5.0-kg object has a velocity of 6.0 m/s, east when it explodes into two 2.5-kg objects.
    After the explosion one of the objects has a velocity of 4.0 m/s at an angle of 50° north
    of east. What is the magnitude and direction of the velocity of the other object after the
    explosion

    2. Relevant equations

    P=MV

    P(i) = P(f)

    3. The attempt at a solution

    P=2.5*4sin(50)

    P(i) = 30
    P(f) = 30

    I got about 3.5m/s, at 48 degrees, which apparently is quite wrong.

    Show your solution so we can see where you went wrong.
