Question

Example #2: Ajet is traveling at 80 m/s when it starts to approach

a runway. It is able to land and park in 10 s. What is its
acceleration?

Answer 1

-8 m/s^2

Step-by-step explanation:

The formula for acceleration is:

a= v^2 - v^1/t

a= acceleration

v^2- final velocity which in this case would be 0 since the jet comes to a stop.

v^1= original velocity which is 80 m/s.

t=time or 10s

Substitute the letters for the numbers and you get this:

a= 0 - 80/10

0 - 80= -80

-80 divided by 10 is -8.

Hope this helps! :)
