1. The problem statement, all variables and given/known data A 4.00-kg cannon ball is flying at 18.5 m/s [0º] when it explodes into two fragments. One 2.37-kg fragment (A) goes off at 19.7 m/s [325º]. What will be the velocity of the second fragment (B) immediately after the explosion? Assume that no mass is lost during the explosion, and that the motion of the fragments lies in the xy plane. 2. Relevant equations p = mv 3. The attempt at a solution K so i got my graph drawn, but because this is an explosion i have no idea how to set up the x and y equations, any help?
