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.
If we consider the vertical component, we can determine how long the ball is in free fall. We can use:
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
