Rotational kinetic energy <span>is the kinetic energy of an object, proportional to the object's moment of inertia and the square of its angular velocity.</span>
The range is
We know that in cinematic problems the velocity in different directions is independent, so on the y-axis, or the y-velocity we have the gravity acceleration changing the velocity, although on the x-axis, or the x-velocity we don't have any acceleration, so the velocity is constant, so, we can use the basic cinematic equations and adapt them for our problem:
We can simplify it, we know that all the initial position on the x-axis is zero, but the initial position on the y-axis is 30, we also know that the initial velocity on y-axis is zero, so
I won't put numbers know, let's do all the manipulation first.
When the ball hit the ground we know that his position is 0 on the y-axis, so
Now we know when the ball hits the ground, so we can use this time on the position equation on the x-axis and find out the distance the ball travelled
That's all! we can just put the values know.

Answer:
The edge length of the empty space between atoms that reside along [100] directions in a BCC crystal of Cs metal is 0.612 nanometers
Explanation:
For Body centered cubic structure (BCC) crystal in direction [100], the edge length of unit cell is calculated with the formula below;
X =
Where;
X is the edge length of the empty space between atoms
R is the radius of the cesium atom = 0.265 nanometers
X = (4*0.265)/(√3)
X = 0.612 nanometers
Therefore, the edge length of the empty space between atoms that reside along [100] directions in a BCC crystal of Cs metal is 0.612 nanometers
