Question

A weight lifter lifts a 360-N set of weights from ground level to a position over his head, a vertical distance of 1.95 m. How much work does the weight lifter do, assuming he moves the weights at constant speed

Answer 1

W= 702 J

Step-by-step explanation:

Given that,

A weight lifter lifts a 360-N set of weights from ground level to a position over his head, a vertical distance of 1.95 m.

We need to find the work the weight lifter do. Work done by an object is given by the formula as follows :

W = Fd

Putting all the values,

W = 360 N × 1.95 m

= 702 J

So, the required work done is 702 J.
