Answer:
The gazelles top speed is 27.3 m/s.
Step-by-step 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
![v=at](https://img.qammunity.org/2020/formulas/physics/middle-school/lou86jrirdw7ahqbib4nzxwyep7kg557ig.png)
Where, v = speed
a = acceleration
t = time
Put the value into the formula
![v=4.2*6.5](https://img.qammunity.org/2020/formulas/physics/high-school/qfmmp4f7pknymx143t6tk0jrkftv47qyjv.png)
![v=27.3\ m/s](https://img.qammunity.org/2020/formulas/physics/high-school/8oyeswfklnsbufreci3kca15x4zpptohlc.png)
Hence, The gazelles top speed is 27.3 m/s.
