I| A Thomson'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 4.2 m/s² for 6.5 s, after which the gazelle 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 19.3 s. How much time would the gazelle take for a 200 m race?

| A Thomson'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 4.2 m/s² for 6.5 s,
after which the gazelle 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 19.3 s. How much time would
the gazelle take for a 200 m race?
