1. The problem statement, all variables and given/known data Im not sure if I did this problem correctly, can someone please reassure me?! 2. Relevant equations Conservation of Linear momentum pf=pi m1v1=m2v2 3. The attempt at a solution M(initial)=100,000 kg M(final)= 100,000kg-15,000kg= 85,000kg V(initial)=20.0m/s V(final)=? P(initial)=P(final) m1v1=m2v2 (100,000)(20.0)=(85,000)(vf) vf=23.53 m/s did i do this correctly?
