Answer 1

Answer:

A cart with mass 20 kg went 50 m in a straight line on a plain and smooth road when a force of 2 N was applied to it. How much work was done by the force?

SOLUTION

Work done by the force = F × S = 2 × 50 = 100J

here is related question answer hope it will help you

now please follow me!!!

Answer 2

Given :-

• Mass of a cart, m = 30 kg
• Distance, s = 60 m
• Force applied, F = 2 N

To find :-

• Work done, W

According to the question,

As we know,

➞ Work done = Force × Distance

Or,

➞ W = F × s

➞ W = 2 × 60

➞ W = 120 J

• So, the work done is 120 Joule.
