Question

Calculate the work done when a 20 N force pushes a cart 3.5 m ? CHECK MY ANSWER PLEASE

20 x 3.5 = 70 J

Answer 1

`70` joules.

Explanation:

Work done `(W)` by a force `(F)` is equal to the dot product of the force and displacement and the cosine of the angle `(theta)` between the two `(S)`.

Hence,

`W=FcdotScos(theta)`

Here, the angle `theta` is `0°`.

So, `cos0°=1`

`:.W=20xx3.5J`

`:.W=70J`. (Answer).

Hope it Helps:)
