An airplane flies horizontally with a constant speed of 175.0 m/s at an altitude of 1300 m. A package is dropped out of the airplane. Ignore air resistance.
The magnitude of the gravitational acceleration is 9.8 m/s2.
Choose the RIGHT as positive x-direction. Choose UPWARD as psotitive y-direction
Keep 2 decimal places in all answers
