1a soccer ball is kicked horizontally off a 22.0-meter high hill and lands a distance of 35.0 meters from the edge of the hill. determine the initial horizontal velocity of the soccer ball.

The initial horizontal velocity of the soccer ball is 16.5 m/s

Explanation:

When we throw a ball, there is a constant velocity horizontal motion and there is an accelerated vertical motion. These components act independently of each other.  Horizontal motion is constant velocity motion.

, so for horizontal motion

for vertical motion

Given:

x = 35 m

Need to find

y = - 22 m

 (negative sign indicates downward motion)

By substituting all known values, we can solve for 't' value as below

Taking square root, we get  t = 2.12 seconds

Now, substitute these to find initial horizontal velocity
