The brakes of a truck cause it to slow down by applying a re- tarding force of 3800 N to the truck over a distance of 830 m. What is the work done by this force on the truck?

Answer:

3.2 MJ

Explanation:

The work done (W) is equal to the force (F) times the distance traveled along the direction of that force (d).

W = Fd

W = (3800 N) (830 m)

W = 3,154,000 J

Rounding to two significant figures, the work done is 3,200,000 Joules, or 3.2 Megajoules.
