Answer:
The baseball takes 0.41 seconds to hit the ground
Step-by-step explanation:
Horizontal Motion
An object thrown horizontally from a height h with an initial speed vo describes a curved path until it hits the ground.
The vertical component of the motion is treated independently of the horizontal component and is ruled exclusively by gravity.
If the object has been traveling during a time t, then the vertical distance is calculated as:
[tex]\displaystyle y=\frac{g.t^2}{2}[/tex]
If we want to know the time the object takes to travel a distance h, then we can solve the equation for t:
[tex]\displaystyle t=\sqrt{\frac{2h}{g}}[/tex]
Since h=0.809 m:
[tex]\displaystyle t=\sqrt{\frac{2*0.809}{9.8}}[/tex]
t=0.41 sec
The baseball takes 0.41 seconds to hit the ground
