Physics problem !!!!!!!!!!!!!!!!!!!!?

An antelope is standing 850m from a river. A cheetah, standing 225m farther from the river than the antelope , sees it, and starts chasing it toward the river. This antelope can run at 35.5 m/s and the cheetah at 26.5 m/s. but, 10s after the chase began, an energy pulse speeds the cheetah at 2.00m/s^2. will the antelope reach the safety of the river or will the cheetah have lunch?? If u kno how to solve can you please explain ?! Thnks !
