Question

1. A car breaks down 2.1m from the shoulder of the road, 200N of force is used to push

the car off the road. How much work has been done on the car?|

Answer 1

420 Joules

Step-by-step explanation:

Applying,

W = Fd.................. Equation 1

Where W = Work done by the car, F = Force applied on the car, d = distance.

From the question,

Given: F = 200 N, d = 2.1 m

Substitute these values into equation 1

W = 200×2.1

W = 420 Joules

Hence the work done on the car is 420 Joules
