A 0.20 kg ball is thrown horizontally at 12 m s⁻¹ towards a wall and rebounds straight back at 8.0 m s⁻¹. The contact time with the wall is 0.040 s. Find the average resultant force on the ball during impact.
- 100 N away from the wall
- 100 N towards the wall
- 50 N away from the wall
- 200 N towards the wall
