A ball is thrown horizontally from the top of a 55.0-m building and lands 103.8 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.) 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.) ____m/s What is the velocity (in m/s) (including both the horizontal and vertical components) of the ball just before it hits the ground? ____ ° counterclockwise from the +x-axis
