A steel ball is projected horizontally from the top of a table.
The ball is projected horizontally at a speed of 
. The ball lands on the ground a horizontal distance of 
from the edge of the table.
Assume that air resistance is negligible.
Calculate the time taken for the ball to reach the ground.
Calculate the vertical component of the velocity of the ball as it hits the ground.
Determine the magnitude and the angle to the horizontal of the velocity of the ball as it hits the ground.
.
.
, and the angle to the horizontal is approximately 
.
