Suppose that a 1.00 cm3 box in the shape of a cube is perfectly evacuated, except for a single particle of mass 1.05 10-3 g. The particle is initially moving perpendicular to one of the walls of the box at a speed of 340 m/s. Assume that the collisions of the particle with the walls are elastic.
(a) Find the mass density inside the box.
(b) Find the average pressure on the walls perpendicular to the particle's path.
(c) Find the average pressure on the other walls.
(d) Find the temperature inside the box.
A batter hits a 0.14kg baseball that was approaching him at 30.0 m/s and, accordingly, the ball leaves the bat at 40.0 m/s in the direction of the pitcher. The ball remains in contact with the bat for 2ms. What is the average force exerted by bat.
