Solve the all parts of given question:
Question: An airplane with a speed of 98.8 m/s is climbing upward at an angle of 73.6 ° with respect to the horizontal. When the plane's altitude is 760 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 don't know how to get that answer for the above question. Please help! Thanks.
