Compute all parts of given problem:
Problem: An airplane with a speed of 74.9 m/s is climbing upward at an angle of 60.3 ° with respect to the horizontal. When the plane's altitude is 771 m, the pilot releases a package.
Part A: Calculate the distance along the ground, measured from a point directly beneath the point of release, to where the package hits the earth.
Part B: Relative to the ground, determine the angle of the velocity vector of the package just before impact.
I need help to determine the angle of the velocity vector of the package just before impact.
