help on physics?

Question

a man who weighs 180 pounds is lifted 200 feet by an elevator. how much work does the elevator do on the man? how much work does the gravitational force do on the man?

Answer 1

W=mgh
I’m not sure how much work is done on the man by the elevator or gravity, however the work done by the elevator against the force of gravity by moving a 180lb man 200 feet upward is

W=mgh=180*200=36000 ft lb

If this man is then crazy to jump from the 200 ft height then the gravity would have done the work W when the poor man hits the ground (ouch!)

Same
W=mgh=36000 ft lb

I hope that helps

Answer 2

Weight = m = 180 lb = 81.65 kg
d = h 200 feet = 60.96 m
g (gravity) on earth = 10 N/kg
w = gravitational force= m × g
w = 81.65 kg × 10N/kg
w =816.5 N

Work done by the elevator on the man
Work = f × d
But f = w
f = 816.5 N
and d=h

Work = f × h
= 8160.5 N × 60.96m
= 49773.84 J
J stands for joule -S.I unit for work
Hope ur satisfied

i've done what i could the way i khnow it
