Question

a cart with mass 30kg went 40m in a straight line on a plain and smooth road when a force of 3N was applied to it. How much work was done by the force? W=3×___ , W=____ J

Answer 1

It will be 120J or Nm

Answer 2

Answer:

Work done, W = 120 joules

Explanation:

It is given that,

Mass of the cart, m = 30 kg

The cart moves a distance of 40 meters in a straight line on a plain.

Force applied on the cart, F = 3 N

Let W is the work done by the force. The product of force and distance is called the work done by the force. It is given by :

$W=F\times d$

$W=3\ N\times 40\ m$

W = 120 Joules

So, the work done by the force was 120 joules. Hence, this is the required solution.
