A 0.40 kg trolley moves at 1.8 m s⁻¹ towards a stationary 0.10 kg trolley on a smooth track. The collision is perfectly elastic. Using conservation of momentum and the relative speed relation for elastic collisions, what is the speed of the 0.10 kg trolley immediately after the collision?
- 2.9 m s⁻¹
- 1.8 m s⁻¹
- 1.2 m s⁻¹
- 3.6 m s⁻¹
