A plane is flying horizontally with speed 233 m/s at a height 5710 m above the ground, when a package is dropped from the plane. The acceleration of gravity is 9.8 m/s2 .A second package is thrown downward from the plane with a vertical speed v1 = 61 m/s. 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.
