Conservation of momentum:
Condition for a perfectly elastic collision:
Using conservation of momentum:
velocity of the first ball, v1i = 2.00 m/s
velocity of the second ball, v2i = -3.60 m/s
m1 = m2 = m
Two billiard balls of equal mass undergo a perfectly elastic head-on collision. If one ball’s initial speed was 2.00 m/s and the other’s was 3.60 m/s in the opposite direction, what will be their speeds and directions after the collision?
