It will take 9.8m/s squared. that is my guesstimate.

Toss a ball upward what is the change in speed each second on the way up and on the way down?
The change in speed each second is the same whether the ball is going upward or downward
What speed must you toss a ball straight up so that it takes 4 s to return to you?
To toss a ball straight up so that it takes 4.0 seconds to return to you, it must be thrown at a speed of 19.6 meters per second. This is because it will have a speed of zero at 2.0 seconds, therefore it must have a speed of 19.6 meters per second for gravity's 9.8 meters per second squared to slow it to zero in 2 seconds.
Is it possible for an object with constant negative acceleration to change the direction in which it is moving?
Sure. Anything you toss with your hand has constant acceleration after you toss it ... the acceleration of gravity, directed downward. If you toss it upward, it starts out with upward velocity, which reverses and eventually becomes downward velocity.
Can an object be accelerating when it speed is zero?
Yes. There can be an instant during a period of acceleration when speed is zero. We can think of two examples right away: 1). Drop an object from your hand. As soon as you release it, downward acceleration begins immediately, but speed is zero. 2). Toss an object (like a baseball or a stone) straight up. Downward acceleration due to gravity begins immediately. At first, its effect is to reduce the upward speed. As soon as the upward speed is all gone, downward speed begins. Acceleration is constant throughout, but at the instant when upward speed becomes downward speed, the speed is zero.
Describe the energy transformations that occur when you toss a ball upward and it falls?
it decreases

How is it that A ball is projected straight up from the ground with a speed of 7.61 meters per second To what maximum height will the ball go when gravity equals 9.80 meters per second squared?
Initial upward speed = 7.61 m/sFinal upward speed (at the point of maximum height) = 0Time to reach maximum height = (7.61) / (9.8) = 0.77653 secondAverage speed during that time = 1/2 ( 7.61 + 0) = 3.805 m/sHeight = 3.805 x 0.77653 = 2.9547 meters (rounded) = about 9.7 feetDoesn't seem like much of a height for a strong toss; but the math looks OK.

What is the probability of getting tails on the first toss and heads on the second toss?
1 in 2 to get tails on first toss 1 in 2 to get heads on second toss To get tails on first toss and heads on second toss, probability is 1/2 x 1/2 = 1 in 4
If you toss a ball upward a certain?
this isn't a question try asking a real question and i might answer it
A ball is thrown upward from the ground with a speed of 36.0 ms At what time after being thrown does the ball have a velocity of zero?
A ball that isn't being held up by anything will accelerate vertically because of the influence of gravity. It's rate of acceleration will be 9.78 meters per second2, directed downward, meaning that each second, its speed in the downward direction will be 9.78 meters per second faster than it was 1 second earlier. When this particular ball is released, its downward speed is negative 36 meters per second. How many times (seconds) does gravity need to increase its downward speed by 9.78 m/s in order to increase its downward speed to zero ? (36 / 9.78) = 3.681 seconds (rounded). That's when the negative downward speed has increased to zero, and becomes a positive downward speed. So it's also the peak of the toss.
Can a geyser suck you in?
No, if anything it would toss you upward with the force and pressure of the water. yes you can get sucked in and you'll be screwed haha
How do you pay toll?
toss change at the stall
What is the easiest way to throw a ball have it stop and completely reverse direction after traveling a short distance?
Toss it gently upward from your hand.
