Athomson's gazelle can run at very high speeds, but its acceleration is relatively modest. a reasonable model for the sprint of a gazelle assumes an acceleration of 4.2m/s2
for 6.5 s, after which the gazelle continues continues at a steady speed.
a. what is the gazelle's top speed?
b. a human would win a very short race with a gazelle. the best time for a 30 m sprint for a human runner is 3.6 s. how much time would the gazelle take for a 30 m race?
c. a gazelle would win a longer race. the best time for a 200 m sprint for a human runner is 19.3s.
how much time would the gazelle take for a 200 m race?
