Answer 1

Answer:a

Step-by-step explanation:

Answer 2

The acceleration of the plane is -2.14 m/s² ⇒ 2nd answer

Step-by-step explanation:

Acceleration is the rate of change of velocity

The unit for acceleration is meters per second square

The rule of the acceleration is: →
`a=(v-u)/(t)`

where a is the acceleration, u is the initial velocity, v is the final velocity

and t is the time

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

We need to find the acceleration of the plane

Lets use the rule above

→ u = 245 m/s , v = 230 m/s , t = 7 seconds

→
`a=(230-245)/(7)`

→
`a=(-15)/(7)=-2.14`

→ The acceleration is -2.14 m/s²

The acceleration of the plane is -2.14 m/s²
