3. [0/5 Points] DETAILS PREVIOUS ANSWERS MY NOTES ASK YOUR TEACHER A ball is thrown horizontally from the top of a 61.5-m building and lands 115.3 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.) (a) How long (in s) is the ball in the air? X s (b) What must have been the initial horizontal component of the velocity (in m/s)? (Indicate the direction with the sign of your answer.) m/s (c) 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 (d) What is the velocity (in m/s) (including both the horizontal and vertical components) of the ball just before it hits the ground? magnitude m/s direction counterclockwise from the +x-axis Additional Materials Reading
