...building 18.0 m away? I have no idea how to even start this could someone please help me?

A baseball thrown at an angle of 60.0 degrees above the horizontal strikes a building 18.0 m away at a point 7.00 m above the point from which it is thrown. Ignore air resistance.

Find the magnitude of the initial velocity of the baseball (the velocity with which the baseball is thrown)

Find the magnitude of the velocity of the baseball just before it strikes the building.

Find the direction of the velocity of the baseball just before it strikes the building.
