A sphere A collides head-on with a second identical sphere B which is stationary. The mass of each sphere is 0.20 kg. Sphere A is travelling at a velocity of 4.0 m/s before the collision and exerts an impulse of 0.50 N s on sphere B.
What is the velocity of sphere A after the collision?
1.5 m/s1.5\text{ m/s}1.5 m/s in the opposite direction to B
1.5 m/s1.5\text{ m/s}1.5 m/s in the same direction as B
2.5 m/s2.5\text{ m/s}2.5 m/s in the opposite direction to B
2.5 m/s2.5\text{ m/s}2.5 m/s in the same direction as B
