Two identical small trolleys A and B move towards each other on a smooth track. Each has mass 0.40 kg and speed 1.5 m s⁻¹ before they collide head-on elastically. After the collision, trolley A moves to the left at 1.5 m s⁻¹. What is the velocity of trolley B after the collision?
- 1.5 m s⁻¹ to the right
- 0 m s⁻¹
- −1.5 m s⁻¹ (to the left)
- 3.0 m s⁻¹ to the right
