Question

A jet plane acceleration along a straight run way from rest to a speed of 140 m/s in 50 seconds when it took off. Calculate:

1- it’s change of velocity
2- it’s acceleration

Please help me it’s emergency

Answer 1

Vf=140 m/s

Vi=0

t=50s

Step-by-step explanation:

1. Acceleration is called change of velocity.

2. a=Vf-Vi/t

a=140-0/50

a=140/50

a=2.8m/s^2
