Question

An airplane traveling 245 m/s east experiences turbulence, so the pilot slows down to 230 m/s. It takes the pilot 7

Answer 1

Answer:a

Explanation:

Answer 2

Answer:

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

Explanation:

Acceleration is the rate of change of velocity

The unit for acceleration is meters per second square

The rule of the acceleration is: → $a=\frac{v-u}{t}$

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

→ $a=\frac{230-245}{7}$

→ $a=\frac{-15}{7}=-2.14$

→ The acceleration is -2.14 m/s²

The acceleration of the plane is -2.14 m/s²
