<h2>Answer:</h2>
Low melting points and electrical conductivity in solids are not common properties of ionic solids.
<h3>Explanation:</h3>
In ionic compounds the electrons involved in the bonding are tightly packed under the influence of electrostatic force of attraction. So the movement of these electrons is very difficult.
In the melting point the bond breaking between the atoms is involved. Hence in case of ionic compound there is a high amount of energy needed to break the ionic bonds.
Electrical conductivity involves the free movement of electrons which is impossible in ionic solids.
So low melting points and electrical conductivity in solids are not common properties of ionic solids.
Answer:
![X(t)= 24 cos (6.28 t +1.57)](https://tex.z-dn.net/?f=%20X%28t%29%3D%2024%20cos%20%286.28%20t%20%2B1.57%29)
And for this case we can write this expression like this:
![X(t) =A cos (wt +\phi)](https://tex.z-dn.net/?f=%20X%28t%29%20%3DA%20cos%20%28wt%20%2B%5Cphi%29)
The velocity would be given by the first derivate and we got:
![V(t) = -wA sin (wt +\phi)](https://tex.z-dn.net/?f=%20V%28t%29%20%3D%20-wA%20sin%20%28wt%20%2B%5Cphi%29)
And the maximum velocity would be:
![V_{max}= |6.28 *24| = 150.72 m/s](https://tex.z-dn.net/?f=V_%7Bmax%7D%3D%20%7C6.28%20%2A24%7C%20%3D%20150.72%20m%2Fs)
Explanation:
For this case we have the following function for the position:
![X(t)= 24 cos (6.28 t +1.57)](https://tex.z-dn.net/?f=%20X%28t%29%3D%2024%20cos%20%286.28%20t%20%2B1.57%29)
And for this case we can write this expression like this:
![X(t) =A cos (wt +\phi)](https://tex.z-dn.net/?f=%20X%28t%29%20%3DA%20cos%20%28wt%20%2B%5Cphi%29)
The velocity would be given by the first derivate and we got:
![V(t) = -wA sin (wt +\phi)](https://tex.z-dn.net/?f=%20V%28t%29%20%3D%20-wA%20sin%20%28wt%20%2B%5Cphi%29)
And the maximum velocity would be:
![V_{max}= |6.28 *24 |= 150.72 m/s](https://tex.z-dn.net/?f=V_%7Bmax%7D%3D%20%7C6.28%20%2A24%20%7C%3D%20150.72%20m%2Fs)
Most likely the baseball because it weighs less therefore with the same force it will go further due to the fact it weighs less it would be easier to apply force and the less it weighs there is also less force acting upon it.
