drag and drop the correct answer choice to each answer blank.
a jet airplane lands on a runway traveling 200 meters per second and comes to a rest over a period of 5 seconds. what is the airplanes acceleration?
drag the number answer into the first blank, and then the correct units into the second blank.
clear all

Explanation:

Step1: Identify initial and final velocities and time

Initial velocity $u = 200\frac{m}{s}$, final velocity $v=0\frac{m}{s}$, time $t = 5s$.

Step2: Use acceleration formula

The formula for acceleration $a=\frac{v - u}{t}$. Substitute the values: $a=\frac{0 - 200}{5}=\frac{- 200}{5}=-40$.

Answer:

-40, $\frac{m}{s^{2}}$
