Question: two balls a and b with masses ma 2mb...
Two balls, A and B with masses mA = 2mB collide elasticaly on a frictionless surface. Before the collision, ball A was at rest and ball B was moving with velocity v along the x- axis.
After the collision , B has only the y- component of the velocity vBy =
Find and speed of ball A and the x components of it's velocity after the collision
