Please right the formula and computatation.

Question

an airplane travels 800 down the runway before taking off.if its stab from rest,move with constant acceleration and becomes airborne in 205, what is the speed in meter/second when it takes off ?

Answer 1

Please use correct english and define your numerical values if you need an answer.

Answer 2

Is this correct?

Distance = 800 m

Time? = 205 (20.5 s?)

20.5 seconds was the only reasonable time I could get from that number. 205 s would be over 3 mins. 2:05 would still be too long.

Starting Speed = 0 m/s

Constant Acceleration

Takeoff Speed = ?

^Is this your question?

(800 m / 20.5 s) x 2 = 78.05 m/s

Answer 3

dont know but if its airborne in 205 seconds it  gonna have problems and have to turn around. and if it took 205 meters to get off the ground they should just abort and go back to the gate
