An airplane with a speed of 82.7 m/s is climbing upward at an angle of 31.8 ° with respect to the horizontal. When the plane's altitude is 871 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.
