Question
3) Cullin is flying his private jet at a constant speed of 750 km/h while David is flying his helicopter due
north. The flight attendant on Cullin's jet begins walking towards the back of the airplane as a constant
speed of 4 m/s relative to the airplane. If the flight attendant observes David moving directly
westward at 38 m/s, what is the velocity of the helicopter in m/s? Hint: You will need to find theta;
don't forget about your ability to use dot products to simplify your equations. [Ans. to Check: VB=200.76
m/s]
