Two billiard balls of identical mass move towards each other and have an elastic collision. If the velocities of the balls are + 20.0 cm/s and -15.0 cm/s, what is the velocity of each ball after the collision? Show all the steps.

A. v1,f= - 15.0 cm/s; v2,f= + 20.0 cm/s

B. v1,f= -10.0 cm/s; v2,f= + 20.0 cm/s

C. v1,f= +20.0 cm/s; v2,f= + 15.0 cm/s

D. v1,f= - 20.0 cm/s; v2,f= +15.0 cm/s

Three billiard balls, all having a mass of 0.170 kg, collide on a horizontal, table. Prior to the collision the red ball is traveling to the right at 1.50 m/s, the green ball is traveling ‘upwards and left’ (45o) at 1.20 m/s, and the yellow ball is traveling ‘downwards’ (90o) towards the crash site at 2.0 m/s. After the collision, both the red and yellow balls are stopped, and the green ball goes off at some velocity. Draw the before...
