A plane is flying horizontally with speed 279 m/s at a height 1390 m above the ground,when a package is thrown downward from the plane with a vertical speed v1=65 m/s. The acceleration due to gravity is 9.8 m/s^2.
Part 1: Neglecting air resistence, what is the horizontal distance traveled by this package? Answer in units of m.
Part 2: Neglecting air resistence, what is the magnitude of the total velocity of the package at the moment it is thrown as seen by an observer on the ground? Answer in units of m/s.
