A drone operator has his drone take off and then start flying due north. The
drone flies 45.3 meters when it collides with a flying bird. The impact makes the
drone veer 24.5° east. It then flies another 22.6 meters before its emergency
auto-landing program causes it to land.
How far, d, and in what direction, e, must the operator walk to retrieve his
drone?
Amelia Earhart learned to fly in a Curtiss JN-4 plane, affectionately known as the Jenny. The Jenny has propellers with 86-inch
diameter blades.
The tip of the blade is 40.7 inches above and 13.9 inches to the left of center. Determine the angle 0, in degrees.
0 =

22 Three basketball players are fighting over
the ball. Julia is pulling with a force of
530 N, Cassandra is pulling with a force
of 690 N, and Laura is pulling with a force
of 620 N. The angle between Julia and
Cassandra is 60°, and the angle between
Cassandra and Laura is 145°. Determine
