Problem: A radioactive atom at rest in the lab decays, sending two smaller nuclei in opposite direction. One fragment has a mass of 8.35 x 10-26 kg and moves at speed 0.770 c.

Part A: If the other fragment has mass of 6.67 x 10-26, what is its speed?

It'd be really helpful if you could show all steps of your work.
