Question

Ruby is out with her friends. Misfortune occurs and

Answer 1

The work done is $2.35\cdot 10^5 J$

Explanation:

The work done by a force on an object is given by:

$W=Fd cos \theta$

where

F is the magnitude of the force

d is the displacement of the object

$\theta$ is the angle between the direction of the force and of the displacement

In this problem, we have

F = 1080 N is the force applied on the car

d = 218 m is the displacement of the car

And assuming the force is applied parallel to the motion of the car, $\theta=0^{\circ}$, and so the work done is

$W=(1080)(218)(cos 0^{\circ})=2.35\cdot 10^5 J$
