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/s^2

Explanation:

initial velocity , u = 245 m/s

final velocity, v = 230 m/s

time taken , t = 7 second

By use of first equation of motion,

v = u + a t

where, a be the acceleration.

Substitute the values of v, u and t

230 = 245 + a x 7

a = - 2.14 m/s^2

the acceleration is negative, it means the airplane is slowing.
