Correct question:-

A force acts for 0.2 sec on a body of mass 2.4 kg initially at rest. The force stops acting but the body moves through 4.0 m in the next 2 sec. Find the magnitude of force.

Solution!!

Let's simplify the question a little more. Our main purpose here is to find the magnitude of force. The magnitude of force equals rate of change of momentum which equals mass multipled with average velocity divided by time.

The mass given is 2.4 kg, time is 0.2 seconds and the body moves for 2 seconds after the force stops acting. The distance that the body moved is 4.0 metre.

First, we have to calculate average velocity and then we will be able to calculate the magnitude of force.

Average velocity = Distance ÷ Time (after the force stopped acting)

Average velocity = 4.0 m ÷ 2 seconds

Average velocity = 2 m/s

Magnitude of force = (2.4 × 2) ÷ 0.2

Magnitude of force = 4.8 ÷ 0.2

Magnitude of force = 24 N
