1. The problem statement, all variables and given/known data An airplane is flying with a velocity of 90.0m/s at an angle of 23 degrees w/ the horizontal. When the plane is 114 m directly above a 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. 3. The attempt at a solution The initial vertical speed of the plane is 35.2 m/s and the initial horizontal speed of the plane is 82.8 m/s. But im confused is the initial velocity of the suitcase going to be the same as the plane's or 0.
