New Problems reloads the page with new variable values in all questions. You must do this after grading the test to rework it another time.
Make sure to enter your answers in the specified units .
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.
