## Homework Statement

You are playing bocci with your friends. You roll your ball towards your opponent's stationary ball (of equal mass) with a certain speed. 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
