Velocities of the bowling balls after the collision

1) A 3 kg bowling ball traveling with a velocity of 3 m/s collides head-on with another bowling ball of the same mass traveling with a velocity of -2 m/s. If the collision is perfectly elastic, the velocities of the bowling balls after the collision is:

a. 2 m/s an -3 m/s
b. 5 m/s and 0
c/-2 m/s and -3 m m/s/s
d. -2m/s and 3

Solution Preview

Answer: d. -2m/s and 3

For a head-on elastic collision
v1f = { ( m1 -m2 )/ m1+ m2) } v1i + ...
