A plane is flying horizontally with speed
193 m/s at a height 2010 m above the ground, when a package is dropped from the plane.The acceleration of gravity is 9.8 m/s^2.

1.What is the horizontal distance from the release point to the impact point?

2.A second package is thrown downward from the plane with a vertical speed v1 = 58 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?

3.What horizontal distance is traveled by this package?

1. 1. 0.5g*t^2 = 2010 m.
4.9t^2 = 2010.
t = 20.3 s. = Fall time.

D = Xo*t. = 193m/s * 20.3s = 3909 m.

2. V=sqrt(Xo^2+Yo^2)=sqrt(193^2+58^2) = 202 m/s.

3. Vo*t + 0.5g*t^2 = 2010 m.
58*t + 4.9*t^2 = 2010.
4.9t^2 + 58t - 2010 = 0.
t = 15.2 s. = Fall time.

D = 193m/s * 15.2s = 2934 m.
