Answer

Answer:

A. $-2\ m/s^{2}$

Explanation:

Step1: Identify the formula

The formula for acceleration is $a=\frac{v - u}{t}$, where $a$ is acceleration, $v$ is final - velocity, $u$ is initial - velocity, and $t$ is time.

Step2: Assign values

Given $u = 245\ m/s$, $v = 230\ m/s$, and $t = 7\ s$.

Step3: Calculate acceleration

Substitute the values into the formula: $a=\frac{230 - 245}{7}=\frac{- 15}{7}\approx - 2\ m/s^{2}$.
