A body A of mass 3 . 0 kg and a body B of mass 10 kg are dropped simultaneously from a height of 14 . 9 m Calculate
their kinetic energies when they are 10 m above the ground

Explanation

To calculate the kinetic energies of body A (mass = 3.0 kg) and body B (mass = 10.0 kg) when they are 10 m above the ground, we can use the principle of conservation of mechanical energy. Here’s a step-by-step solution:

### Step 1: Determine the initial height and the height at which kinetic energy is to be calculated.
- The initial height (h_initial) from which both bodies are dropped is 14.9 m.
- The height (h_final) at which we need to calculate the kinetic energy is 10 m above the ground.

### Step 2: Calculate the height fallen by the bodies.
- The height fallen (h) is given by:
