On a training exercise, an airplane is flying horizontally. Under the angle of 0 60 below the horizontal, its radar detects a remotely controlled truck moving with a constant velocity in the airplane’s direction. An airplane drops a bomb hitting the truck after 0.5 min during which the truck covered a distance of 0.9 km. Air resistance may be ignored. (c) What is the speed of an airplane? (d) At what angle, with respect to the direction of truck’s velocity, does a bomb hit a truck? Ans c 115 m/s d -68.7.
