Assume all gases in this problem are ideal.

$($a$)$ What is the average value of $v_x^2$ in $(\frac{m^2}{s^2})?$

$\frac{m^2}{s^2}$

Does it matter which direction you take to be $x?$

Yes

No

$($b$)$ Applying the methods of this chapter, find the average pressure on the walls $($in $Pa).$

$Pa$ the motion of the ball is in the $x-$direction only the collision between the ball and the wall are inelastic the motion of the ball is isotropic

gravity is negiligible

Van der Waals forces are not negligible
