vf^2=2ad
80^2=2*4*d solve for d.
if takeoff speed is 1/2, then the distance is (1/2)^2=1/4 as far
the takeoff speed for a large airplane is 180 mi/hr(roughly 80m/s0 the plane is capable of accelerating at a rate of 4m/s^2 assume that the plane starts at rest determine the minimum runway length required for this plane to safely take off a smaller airplane requires a takeoff speed that is half as much as the large airplane determine the minimum runway length required for this smaller plane to take off
