How far have you pushed the car?

Question

A car has run out of gas. Fortunately, there is a gas station nearby. You must exert a force of 789 N on the car in order to move it. By the time you reach the station, you have done 2.64 X 10^4 J of work. How far have you pushed the car?

I pushed it 33.5 m!! Oooph!

Work's formula

#W = F*d*costheta#

Theta is zero in this case so it is just F*d (force x displacement).

#2.64*10^4 J = 789 N*d#

#d = (2.64*10^4 J)/(789 N) = 3.35*10^1 m = 33.5 m#

I hope this helps,
Steve
