If an object is thrown up at an initial speed of 9.8 m per sec what would be the final speed upon impact with the ground?

If it leaves your hand with a vertical velocity of 9.8 m/sec, its speed drops to zero after 1 second
and it begins to fall.
After one more second, it returns to the height where it left your hand, and is falling at 9.8 m/sec.
(We don't know how much farther it has to fall to hit the ground, so we don't know how much more
speed it will pick up the rest of the way.)

What is the best way to analyze an object thrown into the air?
whenever an object is thrown in the air we must know the initial velocity with which the object has been thrown.
A 5 kg object is thrown from the top of a building 275m aboce some level ground It is released at a speed of 45 m per s initially along the horizontal direction?
THE QUESTION: 2) A 5 kg object is thrown from the top of a building, 275m aboce some level ground. It is released at a speed of 45 m/s, initially along the horizontal direction. (A) What are the magnitude and direction of its velocity at impact on the ground below (B) what momentum does it have at impact (C) What KE does it have just before impact (D) What is the average force during the impact?
Is it true an object that will hit the ground before an object that is thrown horizontally?
yes, i just test right now
True or false an object that is dropped will hit the ground before an object that is thrown horizontally from the same height?
False, provided the drop occurs no sooner than the throw, and the ground is flat .
Will the object that is dropped hit the ground before an object that is that it is thrown horizontally from the same height?
No. They both hit the ground at the same time, because the VERTICAL component of velocity in both cases is the same.

Will two free fall bodies with different initial speeds reach ground together?
No. The one with higher initial speed will hit the ground first if they are both thrown straight down.
An object thrown vertically up wards from the ground returned back to the ground in 6s after it was thown up if it reached a height of 12m calculate?

If an object is thrown upward with an initial velocity of 32 feet per second from 40 feet above the ground write the height equation?
The height, in feet, above the ground at time t, H(t) = 40 + 32*t - 16*t2
Is acceleration greater when the object is thrown vertically or horizontally?
Acceleration is dependent on the initial velocity of how fast the object is leaving the projectile. The vertical acceleration is greater when the object is falling than when the object reaches the peak in height. However, if the object is thrown horizontally and there is no parabola in its shape then there is not as great of an acceleration.
True or false an object that is dropped will hit the ground before an object that is thrown horizontally from the same height?
False, provided the drop occurs no sooner than the throw, and the ground is flat .
Is an object that is dropped will hit the ground before an object that is thrown horizontally from the same height?
No. They both hit the ground at the same time. This is because the VERTICAL component of velocity in both cases is the same.

What is the projectile theory?
if a body is thrown having initial velocity and make angle with ground this body is known as projectile and the way is calle trajectory
Why every object falls downward while thrown up?
Because there is gravity that why we stay on the ground and not fly in the sky.
