Q. A marble travelling at $100cm/s$ rolls of the edge of a level table. It hits the floor $30cm$ away from the spot directly below the edge of the table. Height of the table is ($g=9.8m/s^2$)

Q. A purple ball rolls off a horizontal table with an initial speed of $3.0m/s$. A red ball rolls off the same table with an initial speed of $1.5m/s$. Both balls fly undhindered toward the horizontal floor that they hit at some horizontal distance from the edge of the table.
How does the horizontal distance for the purple ball compare to the horizontal distance for the red ball?
