Did i do number 2 and 3 correct?
2. A billiard ball (0.62 kg) with a velocity of 2.0 m/s [N] hits another ball and has a velocity of 1.7 m/s [E] after the collision. Determine the impulse on the ball and the average force exerted on it during the collision if the duration of the collision was 0.0072 s. (5 marks)
3. Two billiard balls of equal mass undergo a head on collision. The red ball is travelling at 2.1 m/s [right] and hits the blue ball travelling at 3.0 m/s [left]. If the speed of the red ball after the collision is 3.0 m/s [left], determine the velocity of the blue ball after the collision. (5 marks)
2) 1.6275 (kg.m)/s (East 49.6 degrees South) and the force exerted is 226N (East 49.6 degrees South)
