If an object is thrown up at an initial speed of 9.8 m per sec how long will it take to fall back to 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.
(We don't know how much farther it has to fall to hit the ground.)

What happens to the speed of an object when it is thrown up in the air and when it comes back down?
an object thrown into the air will slow down as it ascends higher into the air until it stops ascending and the speed of the object increases as it falls until it reaches its terminal velocity in air. As an object passes through air, it encounters air resistance which slows down an object moving freely through air. An object will be moving at a slower speed when it hits the ground than it did when it was thrown into the air due to this air resistance.
Why does the speed dcreses when an object is thrown vertically up?
whyh does the sped decreases when an object is thrown vertically up
What relationship exists between the initial velocity and the maximum height reached by an object thrown upward?
Ignoring air resistance, I get this formula:Maximum height of a vertically-launched object = 1.5 square of initial speed/GI could be wrong. In that case, the unused portion of my fee will be cheerfully refunded.
If a rock is dropped and a ball is thrown horizontally at the same initial elevation Which will have the greater speed when it reaches ground level?
at what q from the horizontal should be threw a rock so that it has greatest range
A projectile is thrown with an initial velocity which has a horizontal component of 4 m s What will be its horizontal speed after 3s?
A projectile that is thrown with an initial velocity,that has a horizontal component of 4 m/s, its horizontal speed after 3s will still be 4m/s.
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.
Does uniform speed properly characterize the motion of a heavy object thrown violently downward from a tall building?
No. Regardless of its initial speed, the object still experiences downward acceleration at the rate of 'G'.
What is the definition of initial speed?
Initial speed is the original, beginning speed of an object.
An object is thrown upward will return to its initial position with same speed if air resistance is negligeble what heppened if air resistance is appreciable?
it would be slower

A ball Thrown vertically from the ground level caught 3.0 second latter when it is at highest point by a person on a balcony which is 14 m above the ground determine the initial speed of the ball?

Why does the speed dcreses when an object is thrown vertically up?
whyh does the sped decreases when an object is thrown vertically up
A ball is thrown straight up with an initial speed of 20 m calculate its initial speed take g10 ms-2?
Its initial speed cannot be 20 m, as stated in the question. Secondly, if the initial speed is correctly given, then there is no need to calculate it!
Does different speed of two objects effect the time it takes to reach the ground?
If thrown horizontal from same height the faster object will travel farther horizontally, but time to fall is the same. If thrown straight up, the faster object will take longer to fall
