At the end of most landing runways in airports, an extension of the runway is constructed using a special substance called form Crete. Form Crete can support the weight of cars, but crumbles under the weight of airplanes to slow them down if they run off the end of a runway. g=9.8m/s^2
If a plane of mass1.60×105 kilogram is to stop from a speed of 24.0 m/s on a 150 meter long stretch of form Crete, Find the magnitude of the average force exerted on plane by the form Crete?
