Two billiard balls, one red, one blue, collide with one another perfectly elastically. Prior to the collision, the red ball has velocity UR = (2.96m/s)i while the blue ball is stationary. They both have the same mass, m = 165g. After the collision, the blue ball has speed 1.48m/s and the red ball's velocity is at an angle of 0, 30.0 above the +x-axis. The collision lasts for At=61,5ms. (a) Read parts (b) and (c) below and then define the system you will use in answering those questions. Why does no external impulse need to be considered?
