Assume that a fully loaded plane starting from rest has a constant acceleration while moving down a runway. The plane requires .7 miles of runway and a speed of 160 miles per hour in order to lift off. What is the plane's acceleration?

S = 7mi
u = 0
v = 160mi/hr
v^2 - u^2 = 2aS
160*160 = 2 a (7)
a=1828.6mi/s^2

there is alot extra in the back of who will win .. a/c will will improve up linear.. or otherwords, a persevering with fee of acceleration(with some small fluctions because of tug of the wheels, flaps ) till the thrust=drag. vehicles have Gears, which ability acceleration isn't consistent ordinary. each and each kit has a diverse acceleration fee, till the max skill available is acheived. 0.33 is skill to weight ratio- the extra merchandise weighs, the extra tension is had to enhance up it. Physics one 0 one, F=MA In a quick distance, a vehicle might win, basically because of time required for the engines to spool up, and improve up the plane, yet over an prolonged distance, the acceleration from the plane will over take the vehicle. The quickest street criminal vehicle is recorded at 253mph (Buggati Veyron) . A b747 flies at around 380kts

a = v² / 2.e
v= speed, e=runway length.

This is ridiculously easy if you paid attention in class. I'm not telling and I'm reporting you to your teacher for outsourcing your homework.
