To find the acceleration of the plane, we can use the formula:
acceleration = (final velocity - initial velocity) / time
In this case, the initial velocity is 245 m/s east, the final velocity is 230 m/s east, and the time taken to change speeds is 7 seconds.
Acceleration = (230 m/s - 245 m/s) / 7 s
Acceleration = (-15 m/s) / 7 s
Acceleration ≈ -2 m/s^2
Therefore, the acceleration of the plane is -2 m/s^2. So the closest option is -2 m/s^2.
An 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.)
