Change in linear Momentum(rebound)?

    [SOLVED] Change in linear Momentum(rebound)?

    A superball with a mass of 84.1 g is dropped from a height of 3.6 m. It rebounds to a height of 2.9 m. The acceleration of gravity is 9.8 m/s^2. What is the change in its linear momentum during the collision with the floor? Answer in units of kg m/s.

    I got no idea how to attack this problem.

    The change in linear momentum during collision with the floor is ofcourse the momentum it had just after the bounce minus the momentum it had before it hit the floor.

    Can you find these two momenta from the information given in the problem?

    Do i need to use free-fall to find the velocity?
