An aircraft flies at constant altitude (with respect to sea level) over the South Rim of the Grand Canyon (Fig. 3.40, page 83). Consider a coordinate system such that the positive x axis points to the east, and the positive y axis points north. The aircraft's initial position and velocity are at an angle of and at an angle of where both angles are measured counterclockwise with respect to the positive x axis. The aircraft's acceleration is at an angle of with respect to the positive x axis.
a. What is the velocity of the aircraft after have elapsed?
b. What is the position vector of the aircraft after have elapsed?
