A baseball thrown at an angle of 55.0?^\circ above the horizontal strikes a building 16.0m{\rm m} away at a point 7.00m{\rm m} above the point from which it is thrown. Ignore air resistance.
Part A: find the magnitude of the initial velocity of the baseball (the velocity with which the baseball is thrown)
Part B: find the magnitude of the velocity of the baseball just before it strikes the building
Part C: Find the direction of the velocity of the baseball just before it strikes the building
