Question

An elevator weighing 2500 N ascends at a constant speed of 8.0 m/s. How much power must the motor supply to do this?

Answer 1

Answer #1

Power = work / time = fore* displacement/time = force* velocity
= 2500 * 8 = 20000 watts = 20 KW.

Answer 2

Answer #2

power=Force * velocity
=2500*8=2*10^4 W

Answer 3

Answer #3

P = force . velocity = 2500 x 8 = 20000 W/s

Answer 4

Find the useful power output of an elevator motor that lifts a 2500-kg load a height of 35 m in 17 s, if it also increases the speed from rest to 4.25 m/s. Note that the total mass of the counterbalanced system is 10,000 kg--so that only 2500 kg is raised in height, but the full 10000 kg is accelerated.
