Question

A weightlifter lifts a set of weights a distance of 2.00 m. If the weights have a mass of 60.0 kg and are pushed vertically upward at a constant speed, how much work is done on the weights?

Answer 1

The amount of work done on the weights would be approximately 15.0 Kg of work

Answer 2

1200Nm

Step-by-step explanation:

Work is said to be done if a force applied to an object causes the object to move through a distance. Mathematically,

Work done = Force × Distance

Given distance = 2m

Mass of the body = 60kg

The weight W of the bodies =mass × acceleration due to gravity

W = 60×10 = 600N

Work done = 600×2

Work done = 1200Nm

1200Nm of work is done on the weights
