Answer:
a = 300 m/s²
Explanation:
In 2.5 seconds, a projectile goes from 50 m/s to 800 m/s.
We need to find the acceleration of the projectile. The acceleration of an object is equal to the rate of change of velocity. So,
![a=(v-u)/(t)\\\\a=(800-50)/(2.5)\\\\=300\ m/s^2](https://img.qammunity.org/2022/formulas/mathematics/high-school/x8lesfqwak8pplxuei7oe4bw4vmcm1vvy1.png)
So, the acceleration of the projectile is 300 m/s².
