3 Conservation of energy

During a test flight of an autonomous cargo drone, its total mass is 48 kg.

At its maximum horizontal cruising speed, its kinetic energy ( $E_k$ ) is measured to be 5400 J.

Calculate the velocity ( $v$ ) of the drone at this point.

Use the equation:

v^2 = \frac{2 \times E_k}{m}
