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 4.2 m/s2 for 6.5 s , after which the gazelle continues at a steady speed.

The gazelles top speed is 27.3 m/s.

Explanation:

Given that,

Acceleration = 4.2 m/s²

Time = 6.5 s

Suppose we need to find the gazelles top speed

The speed is equal to the product of acceleration and time.

We need to calculate the gazelles top speed

Using formula of speed

Where, v = speed

a = acceleration

t = time

Put the value into the formula

Hence, The gazelles top speed is 27.3 m/s.
