Question

If you perform 40 joules of work lifting a 10-N box from the floor to a shelf, how high is the shelf?

Answer 1

0.4

Step-by-step explanation:

Answer 2

Answer : Height, s = 4 m

Explanation :

It is given that,

Work done, W = 40 J

Force applied on the box from the floor to a shelf,
`F=10\ N`

We know that the work done is defined as the force applied on an object to produce a displacement on it.

Mathematically, it is written as :

`W=F* s`

s is the height of the shelf

`s=(W)/(F)`

`s=(40\ J)/(10\ N)`

`s=4\ m`

So, the height of the shelf is 4 m.

Hence, this is the required solution.
