At first observation, the airplane is at distance from the station and at angle above the horizon. The airplane is tracked through an angular change in the vertical eastâwest plane; its distance is then. Find the (a) magnitude and (b) direction of the airplaneâs displacement during this period.n elevator without a ceiling is ascending with a constant speed of 10 m/s. A boy on the elevator shoots a ball directly upward, from a height of 2.0 m above the elevator floor, just as the elevator floor is 28 m above the ground. The initial speed of the ball with respect to the elevator is 20 m/s.
