A baseball thrown at an angle of 55.0? above the horizontal strikes a building 17.0m away at a point 6.00m 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.
