An object of mass `40kg` and having velocity `4 m//s` collides with another object of mass `60 kg` having velocity `2 m//s` . The loss of energy when the collision is perfectly inelastic is

Explanation

To solve the problem step by step, we will calculate the loss of energy during a perfectly inelastic collision between two objects.

### Step 1: Identify the given data
- Mass of object A (mA) = 40 kg
- Velocity of object A (uA) = 4 m/s
- Mass of object B (mB) = 60 kg
- Velocity of object B (uB) = 2 m/s
