Answer:
420 Joules
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
