A plane can travel with a speed of 80 mi/hr with respect to the air. Determine the resultant velocity of the plane (magnitude only) if it encounters a: 10 mi/hr cross wind; 60 mi/hr cross wind; 10 mi/hr tailwind; 10 mi/hr headwind. I have no idea what

Consider a plane with a velocity relative to the air of 198 m/s in a westerly direction. If the wind has a speed relative to the ground of 56 m/s (in an easterly direction), how long does it take for the plane to travel from one city to another that is due

A girl ties a toy airplane to the end of a string and swings it around her head. The plane's average angular speed is 2.2 rad/s. In what time interval will the plane move through an angular displacement of 3.3 rad?
