The magnitude of the force is 18.6 N
Explanation:
The work done by a force pushing/pulling an object is given by the equation:
where:
F is the magnitude of the force
d is the displacement of the object
is the angle between the direction of the force and the direction of the displacement
For the block in this problem, we have:
is the work done
d = 1.35 m is the displacement
is the angle
Solving the equation for F, we find the magnitude of the force:
