Homework Help: Bouncing a ball of various heights - Clueless

  1. Nov 5, 2008 #1
    1. The problem statement, all variables and given/known data
    I’m bouncing a ball from a number of different heights, and measure how high they bounce back, i believe using the equations below... well kinda.

    2. Relevant equations
    Ball Falling
    Ball at highest height = mgh
    Drop = h
    When ball hits the bottom= 1/2mv²
    Speed of falling ball= v¹

    Ball bouncing back up
    Ball at highest height = mgh¹
    height bounced = h¹
    Ball at highest point bounced = 1/2mv²
    Speed bounced back = v¹

    3. The attempt at a solution
    I believe this is the maths i need, but have no idea of how to perform the conclusion, with all the heights from the bounced ball I’m going to plot them against a chart and then heat them to certain temperatures to see if there is a pattern.

    If anyone could help or lead me in the right direction it would be much appreciated, as im very confused.
    Thanks, Confuzzled
