Answer

Explanation:

Step1: Identify initial and final velocities and time

Initial velocity $u = 245$ m/s, final velocity $v=230$ m/s, time $t = 7$ s.

Step2: Use acceleration formula

The formula for acceleration $a=\frac{v - u}{t}$. Substitute values: $a=\frac{230 - 245}{7}$.

Step3: Calculate the acceleration

$a=\frac{- 15}{7}\approx - 2.14$ m/s².

Answer:

-2.14 m/s²
