Asked by John Smith

A weightlifter uses energy at a rate of 1000 J per second. He lifts a 100 kg mass at a constant rate
in 1.5 seconds. Find the work done while lifting the mass. Calculate the height the mass was
raised.
Answered by oobleck
force * distance / time = power, so
work = 1000*1.5 = ___ J
100*9.81 * h / 1.5 = 1000
solve for h.
