A ball is thrown horizontally from the top of a 69.0-m building and lands 105.8 m from the base of the building. Ignore air resistance. (Assume the ball is thrown in the +x direction and upward to be in the +y direction.)

How long (in s) is the ball in the air?

What must have been the initial horizontal component of the velocity (in m/s)? (Indicate the direction with the sign of your answer.)

What is the vertical component of the velocity (in m/s) just before the ball hits the ground? (Indicate the direction with the sign of your answer.)
