Q_1
Two small steel balls A and B have mass 0.6 kg and 0.2 kg respectively. They are
moving towards each other in opposite directions on a smooth horizontal table when they
collide directly. Immediately before the collision, the speed of A is 8 m/s and the speed of B
is 2 m/s. Immediately after the collision, the direction of motion of A is unchanged and the
speed of B is twice the speed of A. Find :
a) . The speed of A immediately after the collision
b) . The magnitude of the impulse exerted on B in the collision
