An airplane is flying with a velocity of 224 m/s at an angle of 30.0° with the horizontal, as the drawing shows. When the altitude of the plane is 2.1 km, a flare is released from the plane. The flare hits the target on the ground. What is the angle?

A cup of coffee is sitting in an airplane flying at constant speed and altitude. Mu between cup and table is .36. The plane accelerates, maintaining constant altitude. What is the maximum acceleration that the plan can have without the cup sliding backwards?

You are stationed at a radar base in Warner Robins, GA and you observe an unidentified flying object at an altitude of 2000 m flying towards your radar base at an angle of 20 degrees. How far away from the radar base is that plane (hypotenuse)?
