calculating acceleration of a plane\nan airplane traveling 245 m/s east experienced turbulence, so the pilot decided to slow down to 230 m/s. it took the pilot 7 seconds to get down to this speed. what is the acceleration of the plane? (round your answer to the nearest integer.)\n-2 m/s²\n2 m/s²\n67 m/s²\n-67 m/s²
Answer
# Explanation:
## Step1: Identify acceleration formula
$a=\frac{v - u}{t}$ where $a$ is acceleration, $v$ is final - velocity, $u$ is initial - velocity, and $t$ is time.
## Step2: Assign values
$u = 245\ m/s$, $v = 230\ m/s$, $t=7\ s$.
## Step3: Calculate acceleration
$a=\frac{230 - 245}{7}=\frac{- 15}{7}\approx - 2\ m/s^{2}$
# Answer:
$-2\ m/s^{2}$
