You set up a ramp on your desk at home. Marbles rolling down the ramp and horizontally off your desk consistantly land 52.0 cm from the base of your desk. Your desk is 69.0 cm high. If you pull your desk over to the window of your second story room and "launch" marbles to the ground (6.48 meters below the desk top), how far out into the yard will the marbles land?
I will be happy to critique your thinking.
