1. The problem statement, all variables and given/known data A grenade is rolling due west at 0.954m/s along a floor when it explodes into three pieces of equal mass. The first piece moves at 3.6m/s, 20° [N of W]. The second travels at 5.8m/s, 62° [S of W]. Calculate the velocity of the third piece. 2. Relevant equations P=mv PBefore=Pafter a^2 + b^2= c^2 Tan^-1 to find angle 3. The attempt at a solution My attempt is in the attached image. I was curious if my masses were correct. Since they are all equal, I inputted 1 as my before component, and 1/3 for the 3 after components. Is this correct? And, are my calculations correct as well?
