Asked by Ande

A student eats a dinner containing 8.0 X 10^6 Joules of energy. He wishes to do an equivalent amount of work in a nearby gym by lifting 60 Kg object. How many times must he raise the object to expand this much energy? Assume that he raises it a distance of 2.0 metres each time?
Answered by oobleck
work = force * distance = (60g * 2)n = 8*10^6
Solve for n, the number of reps.

60*2 =8*10*6
