A smooth marble slides with a speed of 12 m/s along a frictionless horizontal table that is 1.5 meters above the floor.

1. Draw a force diagram, make an x/y table, and create a net force equation for the marble while it rolls on the table and then for when it rolls off the table and is in the air.
