Question

You and your friends are driving down the road. Your car breaks down. You have to use a 1,210 N force to push the car 201 m to the side of the road. How much work did you do on the car?

Answer 1

243,210J of work.

Step-by-step explanation:

W=fd

W=1,210J x 201m

W=243,210J

Answer 2

`2.43\cdot 10^5 J`

Step-by-step explanation:

Since the force applied is parallel to the displacement of the car, the work done on the car is simply given by:

`W=Fd`

where

F = 1210 N is the force applied on the car

d = 201 m is the displacement of the car

Substituting numbers into the equation, we find:

`W=(1210 N)(201 m)=2.43\cdot 10^5 J`
