Calculate the amount of work done on a 1.25 N box that is lifted 2.5 m off the floor. Also show units.

Sagot :

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.
