Question

A jet taxiing down the runway receives word that it must return to the gate. The jet is traveling 37.6 m/s when the pilot receives the message. What is the acceleration of the plane if it takes the pilot 5.37 s to bring the plane to a halt ?

Answer 1

7 m/s^2

Step-by-step explanation:

Given that the jet is traveling 37.6 m/s when the pilot receives the message.

And it takes the pilot 5.37 s to bring the plane to a halt.

Acceleration of the plane can be calculated by using first equation of motion

V = U - at

Since the plane is going to stop, the final velocity V = zero.

And the acceleration will be negative

Substitute all the parameters into the formula

0 = 37.6 - 5.37a

5.37a = 37.6

Make a the subject of formula

a = 37.6 / 5.37

a = 7.0 m/s^2

Therefore, the acceleration of the plane to bring the plane to a halt is 7 m/s^2
