Assume all gases in this problem are ideal. A person is in a closed room (a racquetball court) with V = 438 m hitting a ball (m = 42.0 g) around at random without any pauses. The average kinetic energy of the ball is 2.10 J. (a) What is the average value of v in (m2/s²)? m²/s? Does it matter which direction you take to be x? O Yes O NO (b) Applying the methods of this chapter, find the average pressure on the walls (in Pa). Pa (c) Aside from the presence of only one "molecule" in this problem, what are the main assumptions in the kinetic theory of gases that do not apply here? (Select all that apply.) O the motion of the ball is isotropic O van der Waals forces are not negligible O gravity is negligible O the motion of the ball is in the x-direction only O the collision between the ball and the wall are inelastic
