Linear momentum
H2 Physics · JC 2 · Medium · Linear momentum
Two identical small spheres, each of mass 0.20 kg, move directly towards each other on a smooth horizontal surface. Sphere R moves to the right at 3.0 m s⁻¹ and sphere S moves to the left at 1.0 m s⁻¹. They collide and stick together. Using conservation of linear momentum, calculate the speed of the combined mass immediately after the collision.
- 1.0 m s⁻¹ to the right
- 0.50 m s⁻¹ to the right
- 2.0 m s⁻¹ to the right
- 1.0 m s⁻¹ to the left
