a 55 kg high jump athlete leaps into the air in attempt to clear the bar, at the top of the leap the athlete has a total mechanical energy of 3x10 to the power of 10 joules and is moving at 8.33m/s.(adsbygoogle = window.adsbygoogle || []).push({});

Calculate the gravitational potentional energy.

what the hell? how do i get my height?

i have my mass which is 55

and gravity which is 9.8 soo what am i supposed to do?

how do i use mechanical energy too is it also work? how do i use that to get

answer? lol so confusing someone help please ^^
