Question

A construction worker pushes a cement block with a 750 N force for 10 minutes without the cement block moving. How much work did the construction worker do during the 10 minutes

Answer 1

The work done by a system on a different body is equal to the product of the force exerted and the distance that the body has move in parallel to the force exerted. In this item, we have to determine first the distance and multiply it with the given force equal to 750N. 

Answer 2

Answer:

Zero

Explanation:

Work done is defined as the product of force applied and the displacement traveled by the object.

Work = force applied in the direction of displacement x displacement

The SI unit of work is Joule. Work may be positive, negative or zero.

here, force applied = 750 N, displacement = 0 m

So, work done = 750 x 0 = 0 Joule
