How far does the jet travel during the 7 s?

Question

A jet aircraft with a mass of 4,400 kg has an engine that exerts a force (thrust) equal to 60,200 N.

What is the jet's acceleration when it takes off? (Give the magnitude.)

What is the jet's speed after it accelerates for 7 s? (Assume it starts from rest.)

How far does the jet travel during the 7 s?

Answer 1

With solving these problems you want to used the equations for kinematics

knowns:

mass = 4400 kg

force = 60200 N

time = 7 s

v_i = 0 m/s

use the following equations to solve

F= ma

v_f = v_i + at --> v = a t

d = v_it+1/2 a t² ---> d = 1/2 a t²
