A15 g marble moves to the right at 3.5 m/s and makes an elastic head-on collision with a 22 g marble. the final velocity of the 15 g marble is 5.4 m/s to the left, and the final velocity of the 22 g marble is 2.0 m/s to the right.
what is the initial velocity of the 22 g marble?
a) 5.3 m/s to the left
b) 5.3 m/s to the right
c) 4.1 m/s to the right
d) 4.1 m/s to the left
