An airplane traveling 245 m/s east experiences turbulence, so the pilot slows down to 230 m/s. it takes the pilot 7 seconds to slow down to this speed. what is the acceleration of the plane? round your answer to the nearest hundredth. 2.14 m/s2 –2.14 m/s2 67.86 m/s2 –67.86 m/s2

Acceleration,    

Step-by-step explanation:

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

Final speed of the airplane, v = 230 m/s

The pilot takes 7 seconds to slow down to this speed. Let a is the acceleration of the plane. The change in velocity per unit time is called the acceleration of an object. It can be calculated as :

So, the acceleration of the plane is . Hence, the correct option is (b).
