Question 874422: Given: m1v1 = m2v2, where m1 and v1 are the initial mass and velocity,
respectively, and m2 and v2 are the final mass and velocity.
A 21,000 pound train engine is traveling an average speed of
60 mi/hr. It strikes a stationary box car that weights 29,000
pounds. The train engine and box car continue mangled together
at what speed along the track?
