Question

a student wants to push a box of books with the mass of 50 kg in 3 m horizontally towards the location of the shelves where the books will be placed. how much work to bw done to push the box of books in 3 m if the force exerted is 120 N?

Answer 1

The work done is 360 J.

Step-by-step explanation:

Given that,

Mass = 50 kg

Distance =3 m

We need to calculate the work done

The work done is equal to the product of force and displacement.

Using formula of work done

`W = F\cdot d`

`W = Fd\cos\theta`

Where, F = force

D = distance

θ = Angle between force and displacement

Put the value into the formula

`W=120*3\cos0^(\circ)`

`W=360\ J`

Hence, The work done is 360 J.
