An airplane with a speed of 76 m/s is climbing upward at an angleof 44° with respect to the horizontal. When the plane's altitude is 500 m, the pilot releases apackage.
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 velocityvector of the package just before impact.
