The initial velocity and the height of this building are 29 m/s and 780 meters respectively.
<h3>How to calculate the initial velocity?</h3>
In order to calculate the initial velocity, we would apply the second equation of motion:
S = ut - ½at²
200 = u10 - ½(9.8 × 10²)
200 = u10 - 490
u10 = 490 - 200
u10 = 290
u = 290/10
Initial velocity, u = 29 m/s.
Next, we would determine the height of the building:
H = ut + ½at²
H = 29(10) + ½(9.8 × 10²)
H = 290 + 490
Height, H = 780 meters.

Evaporation would be the answer.
Answer:
It is just a theory that multi verse exists. Researchers have found tracers of mirror particles which could only be from other universe.
Explanation:
Its said above.
The complete options are;
A. The average kinetic energy of their particles is the same.
B. The total kinetic energy of their particles is equal.
C. Heat flows from the larger object to the smaller object.
D. Heat flows from the object with higher potential energy to the object with lower potential energy.
Answer:
Explanation:
From the relationship between average kinetic energy and temperature, we have the formula;
E_k = (3/2)kT
Where;
k is a constant known as boltzmann constant.
T is known as temperature
We can see that at the same temperature (T), kinetic energy will remain the same because from the formula, E_k depends km only the temperature.
Thus, average kinetic energy of their particles saying that.
