The ball falls at 9.8m/s^2
Because the ball has an initial fall velocity of 0 we can say the ball fell 1.6m at 9.8m/s^2.
We need to find how long it took the ball to fall.
1.6m = 1/2(9.8)t^2
0.57 = t
Now we need to see how fast the ball was moving horizontally when it fell off the table.
it made it 20 meters before it hit the ground so,
20m = v(.57s)
v is the velocity
divide both sides by .57s
35.09m/s = v
