The magnitude of the force is 18.6 N
The work done by a force pushing/pulling an object is given by the equation:
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:
Learn more about work here:
The Work done by any force is defined as the force applied times the displacement of point of application of force in the direction of force.
This is better represented as a scalar product of Force vector and displacement vector.
Here, the angle between force and displacement is .
∴ Magnitude of force =
