Q. A plane is flying horizontally with speed 279 m/s at a height 1390 m above the ground, while a package is thrown downward from the plane with a vertical speed v1=65 m/s. The acceleration because of gravity is 9.80m/s^2.

Part 1: Avoiding air resistance, what is the horizontal distance travelled by this package? Answer in units of m.

Part 2: Avoiding air resistance, 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.
