Question

2An airplane initially at rest begins to accelerate along the landing strip and will detach from the strip after t1 = 15s acceleration at a distance s1 = 600m from its initial position. Find the acceleration a (assume to be uniform) of the plane.

Answer 1

Again using newtons second law equation
s=ut+0.5a(t^2)
600=0.5*a*(15)^2
a=1200/225 m/s^2
a=5.33m/s^2.
u=0 as the plane is initially at rest.

Answer 2

am i right @ hashmaz

Answer 3

Yes u are right.
