<u>Answer:</u> The average kinetic energy of helium atoms is 
<u>Explanation:</u>
To calculate the average kinetic energy of the atom, we use the equation:

where,
K = average kinetic energy = ?
k = Boltzmann constant = 
T = temperature = 
Putting values in above equation, we get:

Hence, the average kinetic energy of helium atoms is 

We would calculate the magnitude by applying pythagorean theorem:



The angle between two vectors is given by the formula:

In two dimensional, the x axis of vector form is:








That will depend on the coefficient of friction between the sliding surfaces, and also on Zak's weight. We don't have any of that information.
