A pilot flies horizontally at 1300 km/h, at height h! 35 m above initially level ground. However, at time t! 0, the pilot begins to fly over ground sloping upward at angle u! 4.3° (Fig. 2-38).

A helicopter flies 30 km 30 degrees north of east, drops of the supplies to a research team; it then heads 50 degrees north of west traveling 70 km to drop the supplies to a filming crew. What is the resultant displacement of the helicopter?

Plaskett's binary system consists of two stars that revolve in a circular orbit about a center of mass midway between them. This statement implies that the masses of the two stars are equal (see figure below).
