Question

Shot put is a track-and-field event in which athletes propel a metal shot, or ball, by pushing it away from their shoulder. In junior events, shots of different sizes are used for different categories of competitors.

The shot masses and forces applied for four competitors are shown. Which shot will have the greatest acceleration?

5 kg and 30 N

Answer 1

Acceleration = F/m. Compute each:

- 5 kg, 40 N: a = 40/5 = 8 m/s²
- 4 kg, 40 N: a = 40/4 = 10 m/s²
- 6 kg, 30 N: a = 30/6 = 5 m/s²
- 5 kg, 30 N: a = 30/5 = 6 m/s²

Greatest acceleration: 4 kg and 40 N (10 m/s²).
