![6 Ball 1 with a mass of 0.75kg and moving with a velocity of v1 = 1.2î – 3.4j m/s, strikes Ball
2 with a mass of 2.4kg and moving with a velocity of v2 = 0.58j m/s. Assume the collision
is elastic.
a. Calculate the total momentum before the collision
b. Calculate the velocity of Ball 1 after the collision. (you have to do this in the x and y
directions separately.)
c. Calculate the velocity of Ball 2 after the collision.
