A firecracker is tossed straight up into the air. It explodes into three pieces of equal mass just as it reaches the highest point. Two pieces move off at 130 m/s at right angles to each other. How fast is the third piece moving?

2. Relevant equations

3. The attempt at a solution

I'm not sure what to do with this problem, I thought the third piece would be the same as the other two at 130m/s but this is not the case. What is there to do?
