Question

7) How much work does an elevator motor do in lifting a 300. kg

elevator (at constant speed) up 16.5 m with 500.0 kg in the
elevator? W

Answer 1

48510J

Step-by-step explanation:

Given parameters:

Mass of the elevator = 300kg

Height = 16.5m

Unknown:

Work done = ?

Solution:

Work done is defined as the force applied to move a body through a particular distance or height.

Here;

Work done = Force x distance = mgh

m is the mass

g is the acceleration due to gravity

h is the height

Work done = 300 x 9.8 x 16.5 = 48510J
