Compute all given parts of following problem:
Problem: An airplane with a speed of 77.3 m/s is climbing upward at an angle of 31.3 ° with respect to the horizontal. When the plane's altitude is 845 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.
Please break down every step and do not skip over anything - I have been at this problem awhile and keep getting hung up. Thanks for the help!
