Compute all parts of given question:

Question: A baseball is thrown from the roof of a 22.0m tall building with an initial velocity of magnitude 12.0 m/sec and directed at an angle of 53.1 degrees above the horizontal.

Part A: What is the speed of the ball just before it strikes the ground? Use energy methods and ignore air resistance.

Part B: What is the answer for part (a) if the initial velocity is at an angle of 53.1 degrees below the horizontal?

Part C: If the effects of air resistance are included, will part (a) or (b) give the higher speed?

Show all work, use additional paper if necessary for above question.
