A500-kg elevator is raised to a height of 10 m in 10 seconds. calculate the power of the motor.

Power = 4905 W

Explanation:

Power is defined as the rate of work done against the forces acting on the system

here we know that

mass of elevator = 500 m

is moves up against gravity by distance = 10 m

total time taken by it to move = 10 s

so work done against gravity is given as

now power given by motor is given as

0.863333

86%

hope this
