Answer:
≈ 6.68 m/s
Explanation:
A suitable formula is ...
vf^2 -vi^2 = 2ad
where vi and vf are the initial and final velocities, a is the acceleration, and d is the distance covered.
We note that if the initial launch direction is upward, the velocity of the ball when it comes back to its initial position is the same speed, but in the downward direction. Hence the problem is no different than if the ball were initially launched downward.
Then ...
vf = √(2ad +vi^2) = √(2·9.8 m/s^2·1.0 m+(5 m/s)^2) = √44.6 m/s
vf ≈ 6.68 m/s
The ball hits the ground with a speed of about 6.68 meters per second.
__
We assume the launch direction is either up or down.
Answer:
A.Consider and evaluate the consequences of each choice
Explanation:
As you enter the decision-making proccess you would have to see the different options that you have, after this you just have to consider and evaluate the consequences of the different options that you have, in this phase you have to weight the consequences and what it would take to make those decisions.
Density, streak, and geochemical signature through use of inductively coupled plasma mass spectrometry or Fourier transform infrared spectroscopy
Fungi, bacterium

Explanation:
When your head is submerged your skull also vibrates with the sound because it is close to the same density and elasticity as water. Below the surface sound wave pass directly through water and into your head. And above the surface the sound waves only vibrates your ear drum unless the sound is very loud.
