Homework Help: Physics

Posted by Lindsay on Thursday, October 4, 2007 at 6:47pm.

A golf ball released from a height of 1.80 m above a concrete floor, bounces back to a height of 1.06 m. If the ball is in contact with the floor for 4.62 ms, what is the magnitude of the average acceleration a of the ball while it is in contact with the floor?

Quidditch told me that the first steps would be to find the velocity as the ball first makes contact with the floor, and the velocity as the ball leaves the floor. But I'm still unsure how to do this...
