Answer:
Step-by-step explanation:To calculate the work done on the file cabinet, we need to use the formula:
Work = Force x Distance x cos(theta)
where:
Force is the applied force (in Newtons, N)
Distance is the displacement of the object (in meters, m)
Theta is the angle between the direction of the force and the direction of the displacement (in degrees)
In this case, we have:
Force = 45 N
Distance = 3 m
Theta = 0 degrees (since the force is applied in the same direction as the displacement)
Plugging these values into the formula, we get:
Work = 45 N x 3 m x cos(0) = 135 Joules
Therefore, the work done on the file cabinet is 135 Joules.
