4) You were leisurely flying your F-18 when you encounter an alien aircraft. The alien was flying at an altitude of 3 km while you were at an altitude of 600 m. You begin to increase your speed at a rate of 2.0 m/s?. You are traveling at a speed of 750 km/h at the instant when 0 = 45° and at the same instant the alien has a constant velocity of 1,500 km/h. a) Determine the velocity and acceleration vectors (in m/s and m/s², respectively) of the alien as observed by you. [Ans. to Check: VB/A = 208.4 įm/s] b) Determine the time rate of change of the vector r that is between you and the alien ship in m/s. In other words, find r. [Ans. to Check: i = 147.32 m/s] Hint: Do not forget about your ability to dot in different directions to eliminate variables from the equation. c) Calculate the angular velocity of the spaceship relative to you in rad/s. d) Determine the radial and angular accelerations in m/s? and rad/s². [Ans. to Check: ï = 4.86 m/s²] VB 3 km VA 600 m
