You can simply calculate his potential energy at the top of the jump using $$PE=mgh=N*h$$All of that PE will be converted to KE just before he hits the floor.

$$PE=(600N)(0.5m)=300J$$

Oh, well I found the mass to be 61.162 so shouldn't I multiply that by 9.81 and 0.5 or is it the same thing?

anonymous · Answer

Oh yeah it's the same answer xD Thank you!!! :)

If you have Newtons you can skip that...since Newtons = ma = mg
