Consider a particle which bounces vertically in a gravitational field, as discussed in Exercise 6.1. Assume an initial probability distribution, p(p,z, 0) = 108(z)(1.0 p)(p -0.1)(e(x) is the Heaviside function; (x) = 1 for x > 0 and (x) = 0 for x < 0). What is (J, 0, 0)? Sketch p(p, z, t) and p' (J,0,1) for t = 0.4, mass m1, and gravitational acceleration g = 1.
