Answer:
Yes, it is reasonable to neglect it.
Explanation:
Hello,
In this case, a single molecule of oxygen weights 32 g (diatomic oxygen) thus, the mass of kilograms is (consider Avogadro's number):

After that, we compute the potential energy 1.00 m above the reference point:

Then, we compute the average kinetic energy at the specified temperature:

Whereas  stands for the Avogadro's number for which we have:
 stands for the Avogadro's number for which we have:

In such a way, since the average kinetic energy energy is about 12000 times higher than the potential energy, it turns out reasonable to neglect the potential energy.
Regards.

Answer:  
 
Explanation:
Acceleration  is expressed in the following formula:
 is expressed in the following formula:
 
 
Where:
 is the final velocity of the projectile
 is the final velocity of the projectile
 is the initial velocity of the projectile
  is the initial velocity of the projectile
 is the time
 is the time
Solving:
 
 
 This is the acceleration of the projectile
 This is the acceleration of the projectile
 
        
             
        
        
        
The statement that motion is relative is an important concept in physics. The meaning behind this statement is that the motion of an object is relative to either the frame of reference of the observer, or to another distinct frame of reference.
