Question

Determine the quantity of work done when a crane lifts a 100- n block from 2 m above the ground to 6 m above the ground

Answer 1

400J
work done= force × distance

Answer 2

Answer: 400 joules.

Step-by-step explanation:

The minimal force needed to lift a 100N block is a force of 100N.

Now, work is defined as a movement done by a force, so we can write the work as:

W = F*d where F is the force and d is the distance traveled, in this case d = 4m so we have:

W = 100N*4m = 400 joules
