An airplane must reach a speed of 185 mi/h to take off. If the runway is 500 m long, what is the minimum value of the acceleration that will allow the airplane to take off successfully?

First of all, convert 185 mph to 82.7 m/s

Then use the equation
V(final)= sqrt (2 a X)
and solve for a.

X is the runway length in meters.

The answer will be in m/s^2.
