A baseball thrown at an angle of 65.0^\circ above the horizontal strikes a building 16.0 {\rm m} away at a point 5.00 {\rm m} above the point from which it is thrown. Ignore air resistance.
a) find the magnitude of the initial velocity of the baseball.
b) find the magnitude of the velocity of the baseball just before it strikes the building.
c) find the direction of the velocity of the baseball just before it strikes the building.
