After the collision, your ball travels along a path o32 degrees from its original path with a speed of 2.50m/s, while your opponent's ball travels along a path 25 degrees from the original path of your ball. What is the initial velocity of your ball?
Homework Equations
Conservation of Momentum.
P1 + P2 = P1' + P2'
The Attempt at a Solution
Okay, so i tried doing this solution, first i made a diagram of this scenario, but i am not too sure if i drew this correctly. T_T please help me. Here is my attempt of the solution.
So we are trying to find v1
v1 = ?
Pi  initial momentum
Pf  final momentum
Pi = Pf
m1v1 + m2v2 = m1v1' + m2v2'
m1v1 + 0 = m1v1' + m2v2'
.... this is far as i have gone, i was not too sure what to place as my v2' ...
and the masses? hm.... :(. Please Help! T_T
