1. The problem statement, all variables and given/known data A billiard ball going 4 m/s collides with a stationary ball of equal size cause the second ball to move at an angle of 35 degrees at speed of 2.5 m/s --mass=.3 kg What impulse (magnitude and direction) did second ball receive? What about the first ball? What is the final velocity (magnitude and direction) of the frist ball? 2. Relevant equations impulse=kg * m/s final velocity...? 3. The attempt at a solution Impulse of second ball=.3*2.5= .75 kg*m/s Impulse of first ball=.3*4=1.2 kg*m/s Those right? How do I calculate the direction....?
