Given:
The force applied on the box is: F = 1.25 N
The displacement of the box due to lifting is: d = 2.5 m
To find:
The amount of work done on a box.
Explanation:
The work done by the force acting on a particle/object is defined as the product of the force applied and the displacement of the particle/object. Whenever a force causes the box to move to a certain distance, the work is done on the box by the force.
Let F be the force acting on the box and d be the displacement of the box due to applied force. Then, the work done W is given as:
W = Fd
Substituting the values in the above equation, we get:
W = 1.25 N × 2.5 m
W = 3.125 N.m
As 1 Joule (J) is equal to 1 Newton meter (N.m), we get:
W = 3.125 J
Final answer:
The work done on the box is 3.125 J.
