Elvis · Answer 1

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

Frida Bridges · Answer 2

1200Nm

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
