Well, the ball thrown upward is obviously in the air longer before it hits the ground.
It goes up for a while, before its upward speed drops to zero and it starts falling, so
it effectively begins its drop from a higher altitude than a ball that you drop from
your hand or throw horizontally.
I think what you're really wanting to ask is: Which hits the ground first ... a ball thrown
horizontally or a ball just dropped from your hand ? The answer to THAT one is: If you
ignore air resistance, then they both hit the ground at the same time.
For that matter . . . if you ignore air resistance, then it doesn't even matter if one of them
is a Bowling ball and the other one is a ping pong ball or a feather. They still both hit the
ground at the same time !
Weird, no ?
No, the horizontal component of velocity remains constant for an object in projectile motion as long as no external forces act horizontally on the object. In the case of a ball thrown upward, the horizontal component of velocity remains unchanged unless affected by air resistance or other external forces.
The vertical component of the initial velocity of the ball thrown horizontally from a window is zero. The ball's initial velocity in the vertical direction is influenced only by the force of gravity, not the horizontal throw.
The velocity of the ball is 16 feet/sec when it is thrown upward.
The velocity of a ball thrown upward at 16 ft/sec would be 16 ft/sec when it leaves the hand, but it will decrease due to gravity as it moves upward.
The speed of a ball thrown upward upon striking the ground will be the same as the speed at which it was thrown, but in the opposite direction. The speed of a ball thrown downward upon striking the ground will be faster than the speed at which it was thrown due to the acceleration from gravity.

Two vectors that do not lie along the same line. I wish someone would have posted this for me. ^_^

The initial velocity of the ball thrown upward at 16 ft per second is 16 ft/s.
ALOT!!
A ball thrown upward is not considered a free falling body because it initially moves against gravity. Free falling bodies accelerate downward due to gravity alone, while a ball thrown upward has an initial velocity in the opposite direction.
when abody is thrown upward,how many forces act on it?what is the role of the force with which the body has been thrown upward? After a body is thrown upwards, you have gravity pulling it down and friction slowing it.
The initial velocity of the ball is 16 feet per second when thrown upward. The velocity decreases as the ball travels upward due to gravity until it reaches its peak and starts to fall back down.
