An operator at the airport observes on his radar control screen that there is an aeroplane approaching the airport directly from the East. At time t = 0, the aeroplane is at a distance away of d1 = 360 m away from the airport control station and at an angle of θ1 = 400 above the horizontal (See diagram K). He then continues to monitor the plane as it flies through an angular change of Δθ = 1230 towards the West. After this angular change, he sees that the plane is now at a distance of d2 = 790 m away from the control station. SEE ATTACHED DIADRAM What are the components of the aeroplane’s displacement during thiis observation time? WHICH ANSWER IS CORRECT A. (479, 0) m B. None of the other answers C. (-479, 462) m D.

A spaceship travels through deep space to a space station and needs to make a heading correction to get around a nebula. The captain orders the ship to travel 3.1 x 106 kilometers before turning 70 ° and to travel 2.5 x 106 kilometers in that direction. If the captain had not ordered a heading correction, what would have been the magnitude (in kilometers) and the direction (in degrees counterclockwise from the + x-axis) (Counter clockwise: counterclockwise) of the trajectory of the spaceship if it had traveled through the nebula?
An airplane is flying north. It makes a gradual 180° turn (at any instant, the turning angle is less than 90°) at constant speed of 472.2 km/h, changing its direction of travel from north through east to south in 38 s. The centripetal acceleration of the plane for this turn in m/s? is: Answer:
You are standing on the ground at the origin of a coordinate system. An airplane flies over you with constant velocity parallel to the x axis and at a constant height of 8.00 x 10° m. At t = 0, the airplane is directly above you so that the vector leading from you to it is = 8.00 x 10³j m.
