A helicopter is heading N 45° E (i.e. direction angle of 45°) with an airspeed of 18 mph, and the wind is blowing S 17° W (i.e. direction angle of 253°) at 4 mph. Round all numbers in your answers below to 2 places after the decimal point. (a) Find the velocity vector that represents the true heading of the helicopter. Type your answer in component form, (where a and b represent some numbers). Velocity vector of helicopter's true heading: (b) Find the helicopter's speed relative to the ground (in mph). mph (c) Find the helicopter's drift angle, 8. (The drift angle is the number of degrees that the helicopter will end up flying off-course.) Helicopter's speed 8 = degrees
