Homework Statement
A ball is dropped from a height of 9.02 m. After hitting the ground, the ball then rebounds to a height of 1.78 m. What is the coefficient of restitution associated with the ball and ground impact?
Homework Equations
e=(V'-v')/(V-v)
The Attempt at a Solution
I thought maybe this was a trick question and you just do 9.02-1.78=7.24 and that was the answer but I am wrong... I need a bit of guidance on how to proceed with this question.
EDIT:
I just realized I should be using e=v'/v instead since there is only one ball... And I think I have realized that v' is -9.81? Not completely sure though because I also think that that might only be acceleration... CONFUSED lol
I thought that maybe I could use acceleration to find velocity, but I don't have the time...
