Compute all parts of given question:
Question: At an air show, a jet plane has velocity components vx = 725km/h and vy = 515km/h at time 3.85s and vx = 928km/h and vy = 390km/h at time 7.52s.
Part A: For this time interval, find the x component of the plane's average acceleration.
Part B: For this time interval, find the y component of the plane's average acceleration.
Part C: For this time interval, find the magnitude of its average acceleration.
Part D: For this time interval, find the direction of its average acceleration.
I need help to find the magnitude of its average acceleration.
