An airplane with a speed of 77.1 m/s is climbing upward at an angle of 70.4 ° with respect to the horizontal. When the plane's altitude is 861 m, the pilot releases a package.
(a) Calculate the distance along the ground, measured from a point directly beneath the point of release, to where the package hits the earth.
(b) Relative to the ground, determine the angle of the velocity vector of the package just before impact.
