An object rolls off a tabletop with a horizontal velocity v0x = 18 m/s. The table is at a height y0 = 1.2 m, above the floor. Use a coordinate system with its origin on the floor directly beneath the point where the object rolls off the table, its horizontal x-axis lying directly beneath the object’s trajectory, and its vertical y-axis pointing up. What's the horizontal distance, in meters, from the edge of the tabletop to where the object lands?

Expert Solution
Introduction:
We are given initial horizontal velocity of object. We are also given its initial height. The origin is set at point directly below the table top at ground from where the object rolls off. We first find time of flight. We then use this time to find horizontal distance.
