(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known dataA firecracker (mtot = 0.70 kg), sitting on a frozen pond, explodes into three pieces, each of which moves horizontally. Piece 1 (m1 = 0.20 kg; v1 = 100 m/s) moves at a right angle to piece 2 (m2 = 0.20 kg; v2 = 125 m/s). What is the speed of the third piece?

2. Relevant equationsmv=p=j=ft

3. The attempt at a solutionm(tot)v1+v2+v3=ft i think t=v(final)/a and a would be equal to gravity but iam just not sure. thanks for help!
