The angular acceleration of a pulley is described under the equation,
So things clearing,
b) For point B it is necessary to make a sum of Forces,
In this way,
(1)
For block 2, we have the following relationship,
(2)
So,
(3)
Substituting (1) and (2) in (3)
So,
<em>**Note that</em> 
c) For this point we need to use (1)
using (2)

The answer is a dense substance that is hard and incompressible.
A crystal or crystalline solid is a solid material whose constituents (such as atoms, molecules, or ions) are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions.
Hoped I helped!
The best thing to do in this case is to redo the experiment and re record the info, it has to be precise and accurate so you also have to check if your procedure is correct. If the results are both accurate and precise then you have to report your findings to the committee of that specific field. <span />
Answer:
Acceleration from gravity is always constant and downward, but the direction and magnitude of velocity change. At the highest point in its trajectory, the ball has zero velocity, and the magnitude of velocity increases again as the ball falls back toward the earth
