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 ?
If a ball is thrown horizontally from a window on the second floor of a building, the vertical component of its initial velocity is zero.
less than the speed it had when thrown upward.
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.
6.261 m/s
It comes back downward! :) enjoi!

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

ALOT!!

zero
If a ball is thrown vertically upward with a velocity of 160 ft/s, then its height after t seconds is s = 160t - 16t^2. If a ball is thrown vertically upward with a velocity of 160 ft/s, then its height after t seconds is s = 160t − 16t^2.
The kinetic energy will be decrease because when the body thrown in upward direction the gravitation force will be act in opposite direction which reduce the velocity.so the velocity will decrease.
A stone is thrown upward at 27 m/s from a cliff that is 125m relative to the sea? How long will it take to hit the water
