Q.2 An aeroplane starts is descent at an altitude of H = 2500 m, and when it is L = 5000 m away from the airport runway. The descend path of the aeroplane is described using the polynomial y = ax3 + bx2 + cx + d , where y is altitude, and x is horizontal distance. H L The areoplane begins its descend from a level position and lands at a level position. (a) Solve for the coefficients a, b, c, and d. (b) If the aeroplane maintains a constant forward speed (de = u = constant ) and the magnitude of the vertical acceleration () is not to exceed a constant A, show that SHM? SA (c) If acceleration A = 0.01m/s2, H = 4572 m and u = 4570 km/hr, how far from the airport should the pilot begin the descent ? 2+2 a
