Kinetic energy KE = 1/2 m v^2 (mass in kg).

Compute each:

- 100 g (0.1 kg) at 10 m/s: KE = 0.5·0.1·10^2 = 5.0 J
- 10 g (0.01 kg) at 2 m/s: KE = 0.5·0.01·2^2 = 0.02 J
- 100 g (0.1 kg) at 15 m/s: KE = 0.5·0.1·15^2 = 11.25 J
- 10 g (0.01 kg) at 1 m/s: KE = 0.5·0.01·1^2 = 0.005 J

Least kinetic energy: the ball with mass 10 g falling at 1 m/s (0.005 J).
