Q1. An airplane is flying with the velocity of 85.0 m/s at an angle of 20.0 degrees above the horizontal. When the plane is a distance 107 m directly above the dog that is standing on level ground, a suitcase drops out of the luggage compartment. How far from the dog will the suitcase land? You can ignore air resistance.
Q2. A golf ball with an initial speed of 73.8 m/s lands exactly 141 m down range, on the level course. Neglecting air friction, what minimum projection angle would achieve this result? The acceleration by reason of gravity is 9.8 m/s2.
