A jet aircraft is flying at constant altitude. At t1 = 0 it has components of velocity vx = 150 m/s and vy = 130 m/s. At time t2 = 30.0 s the components of the velocity are vx = -120 m/s and vy = -50 m/s.
a. Sketch the velocity vectors at each time.
b. What is the change in velocity during this time interval?
c. What are the components of the average acceleration during this interval?
d. What is the acceleration's magnitude and direction during this time interval?
