Homework Help: physics

Cheetahs can sustain speeds of 25 m/s over short distances. One of their prey is Thomson's gazelle, with top speed about 22 m/s.
If a 52kg cheetah running southward at top speed grabs and holds onto a 23kg gazelle running westward at 22 m/s, find the velocity of these animals just after the attack. Assume that eastward is a positive x-direction and northward is a positive y-direction.
