Question

An airplane traveling at 60 m/s comes to a stop in 10 seconds. Calculate the airplane’s acceleration. Show the appropriate formula and show your work with units in order to receive credit. (Chapter 2 – Pages 57-58)

Answer 1

Airplanes acceleration is
`-6 m/s^2`

Step-by-step explanation:

Acceleration is defined as the rate of change of velocity with time.

Acceleration is defined as the rate of change of velocity. It is given by the equation

`a= (v-u)/(t)`

In the given question the airplane travelling at the speed of 60 comes to a stop in 10 seconds.

Thus initial velocity u=
`60 m/s`

Final velocity v=
`0 m/s`

time t=
`10 s`

Acceleration
`a= (0-60)/(10)`

=
`(-60)/(10)`

=
`-6 m/s^2`
