When traveling on an airplane you get meals on a serving tray that has large coefficients of static and kinetic friction between the tray and dishes on it. Assume the airplane is moving from left to right. Assume also that the tray is parallel to the velocity of the airplane. Draw the vectors starting at the black dot. The location, orientation, and relative length of the vectors will be graded. The exact length of the vectors will not be graded. a. Draw a force diagram for a cup on a serving tray as seen by a stationary observer on Earth if the airplane is flying horizontally at constant speed; the cup is at rest on the tray. b. Draw a force diagram for a cup on a serving tray as seen by a stationary observer on Earth if the airplane is on a runway and slowing down; the cup is at rest on the tray. c. Draw a force diagram for a cup on a serving tray as seen by a stationary observer on Earth if the airplane is on a runway and slowing down; the cup is sliding. Next to the force diagram draw an arrow that shows the velocity of the cup relative to the airplane. d. Draw a force diagram for a cup on a serving tray as seen by a stationary observer on Earth if the airplane is on a runway and speeding up; the cup is at rest on the tray. e. Draw a force diagram for a cup on a serving tray as seen by a stationary observer on Earth if the airplane is descending at constant speed at an angle 30∘ with respect to horizontal; the cup is at rest on the tray. f. Draw a force diagram for a cup on a serving tray as seen by a stationary observer on Earth if the airplane is slowing down and descending at an angle 30 ∘ with respect to horizontal; the cup is at rest on the tray.
