Question

In loading a truck a man lifts boxes of 100n each through a height of 1.5 m. How much work does he do in lifting 1 box?

Answer 1

We know that the work = force X distance

                                  W = FXS ------ (1)

In this question,

  Force = F = 100N

  Distance = S = 1.5m

Now we can substitute above values for equation (1)

            W = 100 X 1.5

            W = 150 Joule

Answer : work done by the man = 150 J

Answer 2

The work done by the man in lifting 1 box is 150 joules.

Explanation:

Given that,

Weight of the boxes, W = 100 N

Height or displacement of the boxes, d = 1.5 m

To find,

Work done by the man in lifting 1 box.

Solution,

Work done is given by the product of force and displacement. It is given by :

$W=F\times d$

$W=100\ N\times 1.5\ m$

W = 150 Joules

So, the work done by the man in lifting 1 box is 150 joules.
