A space probe with a rest mass of 8.3×107 kg and a speed of 0.49c smashes into an asteroid at rest and becomes embedded within it. If the speed of the probe-asteroid system is 0.27c after the collision, what is the rest mass of the asteroid?
my answer was wrong & i dont know how to figure it out!!

If it's a significant fraction of c like that you can't use Newtonian formulae.
Try using conservation of energy and e=mc^2.
Otherwise, look up special relativity momentum
