A body of mass m is moving with a uniform velocity U. A force is applied on the body due to which its velocity increases from u to v: How much work is being done by the force ?

Explanation

To solve the problem of how much work is being done by the force when a body of mass \( m \) increases its velocity from \( u \) to \( v \), we can follow these steps:

### Step 1: Understand the relationship between work, force, and displacement
Work done by a force is defined as the product of the force and the displacement in the direction of the force. Mathematically, this is expressed as:
\[ W = F \cdot s \]
where \( W \) is the work done, \( F \) is the force applied, and \( s \) is the displacement.
