IN 1993, cuban athlete javier sotomayor set the world record for the high jump.The gravitational potential energy associated with his jump was 1970 J. His mas is 82kg. How high did he jump?
Well , Potential Energy = mgh
m=mass = 82
g=acceleration of gravity=9.80m/s^2
h=what we are looking for
PE=mgh
PE/(mg) = h
Substitute in the values:
1970/(82 x 9.8) = h
2.451 meters <<<<<<--------SORRY ! I had a typo in my original answer of 2.541 meters
