An aircraft flies at constant altitude (with respect to sea level) over the South Rim of the Grand Canyon (see figure below). 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 1370 m at an angle of 145° and 55.0 m/s at an angle of 55.0° where both angles are measured counterclockwise with respect to the positive x axis. The aircraft's acceleration is 4.3 m/s2 at an angle of 195° with respect to the positive x axis. (Express your answers in vector form.) (a) What is the velocity of the aircraft after 7.00 s have elapsed? vf =
