Question

A force of 1000N was applied to stop a car that was moving with a constant velocity. The car stopped after moving through 10m. How much is the work done?

Answer 1

Given conditions ⇒

Force (F) applied to stop the car  = 1000 N
Distance covered (d) by the car after the force applied = 10 m. 

Now, For Work done, 

Work done by the force to stop the car = Force applied on the car × Distance covered by it after the force applied. 
 ∴ W = F × d
 ⇒ W = 1000 × 10
 ∴ W = 10000 J. 
   or W = 10 kJ.


Hence, the work done by the force to stop the car is 10 kJ (or kilo Joule) or 10000 J.


Hope it helps.

Answer 2

Explanation:

W = F × D

W= 1000 × 10

W= 10000 J

Hence work done is 10 kilo joule or 10000 J
