A ball of mass m is thrown in air with speed `v_(1)` from a height `h_(1)` and it is at a height `h_(2)(gth_(1))` when its speed becomes `v_(2)` . Find the work done on the ball the air resistance.

Explanation

To find the work done on the ball by air resistance, we can use the work-energy theorem, which states that the total work done on an object is equal to the change in its kinetic energy.

Let's break down the solution step by step:

### Step 1: Understand the Problem
We have a ball of mass \( m \) thrown upwards from a height \( h_1 \) with an initial speed \( v_1 \). It reaches a height \( h_2 \) with a speed \( v_2 \). We need to find the work done by air resistance during this motion.

### Step 2: Apply the Work-Energy Theorem
