|| A cheetah spots a Thomson’s gazelle, its preferred prey, and leaps into action, quickly accelerating to its top speed of 30 m/s, the highest of any land animal. However, a cheetah can maintain this extreme speed for only 15 s before having to let up. The cheetah is 170 m from the gazelle as it reaches top speed, and the gazelle sees the cheetah at just this instant. With negligible reac- tion time, the gazelle heads directly away from the cheetah, accelerating at 4.6 m/s² for 5.0 s, then running at constant speed. Does the gazelle escape? If so, by what distance is the gazelle in front when the cheetah gives up?

Transcribed Image Text:53. || A cheetah spots a Thomson's gazelle, its preferred prey, and
BIO leaps into action, quickly accelerating to its top speed of 30 m/s,
the highest of any land animal. However, a cheetah can maintain
this extreme speed for only 15 s before having to let up. The
cheetah is 170 m from the gazelle as it reaches top speed, and the
gazelle sees the cheetah at just this instant. With negligible reac-
tion time, the gazelle heads directly away from the cheetah,
accelerating at 4.6 m/s² for 5.0 s, then running at constant speed.
Does the gazelle escape? If so, by what distance is the gazelle in
front when the cheetah gives up?
