An airplane undergoes the following displacements: First, it flies 66 km in a direction 30° east of north. Next, it flies 49 km due south. Finally, it flies 100 km 30° north of west. Using vector components, determine how far the airplane ends up from its starting point.

A test rocket is fired straight up from rest with a net acceleration of 20.0 m/s2
upwards. After 4.00 seconds the motor turns off, but the rocket continues to
coast upward with no appreciable air resistance (deaccelerating). What
