Homework Statement
A golf ball bounces down a flight of steel stairs, striking each stair on the way down. The ball starts at the top step with a vertical velocity component of zero. If all the collisions with the stairs are elastic, and if the vertical height of the staircase is 3.00 m, determine the bounce height when the ball reaches the bottom of the stairs. Neglect air resistance.
Homework Equations
Momentum before collision = momentum after collision
The Attempt at a Solution
I tried setting up equations, but only got as far as mgh = 1/2mv^2 because of conservation of ME.
