 1
The airspeed of a plane is km/h and the pilot keeps the plane pointed north. A wind is blowing km/h from the west. Determine the speed (in km/h) of the plane relative to the ground.

 2
How many degrees east of north is the airplane in the previous question traveling relative to the ground?

 3
The airspeed of a plane is km/h and the pilot keeps the plane pointed [N ºE]. A wind is blowing km/h from the west. Determine the speed (in km/h) of the plane relative to the ground.

 4
For the plane in the above question, how many degrees east of north is the plane's velocity relative to the ground?

 5
A rock is thrown horizontally at m/s from the top of a cliff m high. How many seconds does the rock take to reach the ground?

 6
What is the horizontal displacement (in m) of the rock in the previous question?

 7
A ball is thrown from the top of a building with a horizontal velocity of m/s, and lands m away from the base of the building. How high (in m) is the building?

 8
A gun shoots a bullet at m/s at an angle of º above the horizontal. The bullet embeds into a tree at the same height as it left the muzzle. Neglecting air resistance, determine the bullet's time of flight in seconds.

 9
Determine the bullet's horizontal displacement, or "range," (in km) in the previous question.
