Question

A 102 kg man climbs a 5.0-meter-high stair case at constant speed. How much work does he do?

Answer 1

Work done = 4,998 J

Step-by-step explanation:

Given:

Mass m = 102 kg

Height h = 5 m

Find:

Work done

Computation:

Work done = mgh

g = gravitational acceleration = 9.8m/s²

Work done = (102)(9.8)(5)

Work done = 4,998 J
