The motor hauling the cable is capable of developing no more than 40 kw of power. if the motor takes 30 sec to haul the car up at its maximum power output, and the motor...

answers:
Ash say: Work = Power x Time
Also Work = ΔPE
ΔPE = Power x Time
mgh = 40000 x 30
h = (40000 x 30)/(1100 x 9.8)
h = 111 m
