1. The problem statement, all variables and given/known data I am currently working on a lab that deals with a bouncing ball where I need to find the KE and impulse yet I have no mass given. 2. Relevant equations PE=mgh KE=1/2mv p=mv 3. The attempt at a solution I have calculated KE by first finding the PE in the middle of the bounce where they will be equal. So half way from the highest point I calculated PE using PE=mgh. Then assumed KE was the exact same. I am however confused as to how to calculate impulse since I have no mass, just a KE value.
