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 whole number.)

Acceleration of the plane,

Explanation:

It is given that,

Initial speed of the airplane, u = 245 m/s

Final speed of the airplane as it slows down, v = 230 m/s

It took the pilot 7 seconds to get down to its final speed. Let a is the acceleration of the plane. We know that the rate of change of velocity of an object is called its acceleration. The mathematical expression is given by :

The negative sign shows that the airplane is slowing down or deceleration. Hence, this is the required solution.

since you're a real machine, your ama is always less than your ima, because you can never totally eliminate friction.
