A 25000 kg bowling ball moving at 40 m/s on a path angled at 17° hits a 10000 kg bowling ball moving at 25 m/s on a path angled at 60°, causing the lighter ball to be deflected off to an 80° angle. Assuming this is a two-dimensional perfectly elastic collision, what are the final velocities of the balls?

are these wrecking balls, or do you mean grams instead of kg?
