If Sam throws the baseball with higher speed:
A. how will the time it takes to hit the ground be affected?
B. how will the horizontal distance be affected?

A. the time wont be affected. gravity would work just the same.
B. the distance would be affected because it will go farther because the speed is higher, but the gravitational pull is the same. it would go a greater distance.
C. if this is your homework, you could've answered those two questions in the time you took to type them. just think!

A. time is the same. Think about the y-component when the ball is thrown horizontally; it's the same. thrown w/ higher speed = more v horizontally; vertical motion is the same as b4. And the vertical motion's the only thing that determines whether it will hit the ground.
B. horizontal distance will obviously be longer: you threw w/ greater v, so greater x with same t. The same t because t is dependent on the y-motion (vertical), which determines when ti will hit the ground. Same t, bigger v:
x = vt
t is a constnat; so x varies with v. greater x = greater v

The time would remain the same and distance would increase.
Basically, the time is the vertical velocity divided by 9.81, which doesn't change with a horizontal change, and the distance is the time multiplied by the initial horizontal velocity (the speed of the ball when he throws it)

Is the wind blowing?
Are there birds flying nearby? Because, if the ball bounces off of a bird, that might affect the time...
Also, are there trees down below? Because if the ball lands in a tree, it might never hit the ground.
