Question

A fighter jet of mass 20800 kg with two engines each having thrust of 40 kN on runway starts from rest and accelerates at a rate of a = a- kv2, where a constant acceleration from engine thrust in m/s2, k is the aerodynamic lag coeff ent in m and v is the velocity in m/s. The k value can be taken as 0.0005 m land the takeoff velocity of the fighter can be taken as 276 km/h. Just after the take of the pilot adjusted the fighter jet path to y = 0.003x2 with constant upward velocity 14 m/s to reach a height of 1000 m. Consider g = 9.81 m/s2 [Hint: Incorporate average velocity judiciously).

The runway length utilized by the fighter jet in mis

The total time taken (from rest) by the fighter jet to reach the height of 1000 m​
