The displacement of the book is 5 meters
Explanation:
The work done by a force when moving an object is given by:
[tex]W=Fd cos \theta[/tex]
where :
F is the magnitude of the force
d is the displacement
[tex]\theta[/tex] is the angle between the direction of the force and the displacement
In this problem, we have:
W = 500 J is the work done by Maria
F = 100 N is the force applied by Maria
[tex]\theta=0^{\circ}[/tex], assuming the direction of the force is parallel to the displacement
So we can rearrange the equation to solve for d, the displacement:
[tex]d=\frac{W}{F cos \theta}=\frac{500}{(100)(cos 0)}=5 m[/tex]
So, the book was moved 5 meters.
