in a straight line on a plain and
smooth road when a force of 2N
was applied to it. How much work
was done by the force ?​

Answer 1

Answer:

100 J

Explanation:

Work done = Force . displacement = 100 J

Answer 2

Answer:

Explanation:

Given :-

Mass of the car = 20 kg.

Distance covered = 50 m. 

Force applied on the cart = 2 N. 

To Find :-

The work done by the force

Formula to be used :-

Work done = Force applied × distance covered. 

Solution :-

⇒ Work done = Force applied × distance covered. 

⇒ Work done = 2 × 50

⇒ Work done = 100 J.

Hence, the work done by the force is 100 J.
