If a ball is lifted 2 meters off the ground and 5 Newtons of force were needed to move it,
what amount of work has been done? :3

Respuesta :

Answer:

W = 98 J

Explanation:

Given hat,

Force, F = 5 N

It is lifted 2 m off the ground.

We need to find the amount of work done. We know that, the work done by an object is given by the product of force and displacement. So,

W = Fd

or

W = mgd

Put all the values,

W = 5 × 9.8 × 2

W = 98 J

So, the work done is equal to 98 J.
