Sphere A of mass 0.25kg moves with speed 5m s−1 in a direction 40∘ above the horizontal towards sphere B of mass 0.50kg. Sphere B is moving horizontally towards A with speed 2m s−1. At the moment of impact the line of centres is horizontal. The coefficient of restitution is 0.7.
a. (i) Determine the horizontal component of velocity of sphere A immediately after the collision.
b. (ii) Determine the horizontal component of velocity of sphere B immediately after the collision.
