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

The acceleration rounded off to the nearest 100th is: -2.14 m/s^2

Step-by-step explanation:

Acceleration can be defined as the change in velocity over time.

The acceleration is negative in case of slowing down as the velocity goes from a higher value to lower value.

The formula for acceleration is:

$a=\frac{Change\ in\ velocity}{time}\\a=\frac{v_f-v_i}{t}\\Here,\\v_f\ is\ final\ velocity\\v_1\ is\ initial\ velocity\\t\ is\ time$

Given

v_f = 230 m\s

v_i = 245 m\s

t = 7

Putting the values

$a=\frac{230-245}{7}\\=\frac{-15}{7}\\=-2.14\ ms^{-2}$

Hence,

The acceleration rounded off to the nearest 100th is: -2.14 m/s^2
