Two small children decide it would be fun to toss a couple of large cats at each other. Cat A (7kg) is thrown at 7m/s and cat B (6.1kg) is thrown at 2m/s. When they collide the cats stick together. How fast is the cat mess going after the collision?

V=4.7m/s

Explanations:

Let Ma mass of cat A=7kg

Va velocity of cat A=7m/s

Mb mass of cat b=6.1kg

VB velocity of cat b=2m/s

From conservation of linear momentum

MaVa+MbVb = (Ma+Mb) V

7*7+6.1*2 = (7+6.1) V

61.2=13.1V

V=4.7m/s
