A ball rolls with a speed of #2.0m/s# across a level table that is #1.0m# above the floor. Upon reaching the edge of the table, it follows a parabolic path to the floor. How far along the floor is the landing spot from the table?

We need to consider vertical and horizontal components.
Explanation:
If we consider the vertical component, we can determine how long the ball is in free fall. We can use:
S=1m
And u, initial velocity in vertical direction, is 0m/s
And we can take acceleration as 9.81
So t= 0.45s
In the horizontal direction, there is no acceleration so we can simply use
Hence distance along the floor from the table is
