A cannon fires a ball horizontally with a velocity of 240 m/s. If the cannon is in a 44 meter tall tower and the ground below is flat, then (a) How long does the ball take to hit the ground after being fired? (b) At what horizontal distance from the cannon does the ball hit the ground? and (c) What are the horizontal and vertical components of the ball's velocity just before it hits the ground?
