Ball A, with a mass of 2 kg moves with a velocity of 4 m/s to the right. It collides with a stationery ball B, with a mass of 2.5 kg. After the collision, ball A moves in a direction of 62° up from its original
direction, while ball B moves in a direction of 28° down from its original direction. Calculate the velocity
of each ball after the collision?
A) 1.7 m/s and 6.0 m/s
B) 2.45 m/s and 5.25 m/s
C) 3.1 m/s and 4.6 m/s
D) 3.85 m/s and 3.85 m/s
