A jet plane is flying at a constant altitude. At time I, = 0 it has components

Question:

A jet plane is flying at a constant altitude. At time I, = 0 it has components of velocity v, = 90 m/s Vy = 110 m/s. At time 12 = 30.0s the components are v, = -170m/s, Vy = 40m/s.
(a) Sketch the velocity vectors at t, and f2. How do these two vectors differ? For this time interval calculate
(b) The components of the average acceleration, and
(c) The magnitude and direction of the average acceleration.
