A cheetah is walking at a speed of 1.10 m/s when it observes a
gazelle grazing at rest 301.0 m directly ahead. The cheetah begins
to accelerate at 9.55 m/s2 . Two seconds later, the gazelle notices
the cheetah coming toward it and starts running away, accelerating
at 7.00 m/s2 . How long does it take (in seconds) for the cheetah
to catch the gazelle from the moment that the cheetah starts
accelerating?
