The phase space trajectory of a single particle falling freely from height is?

Answer 1

Explanation:

plz refer the above ..i hope it is helpful.

Answer 2

Explanation:

At t = 0, p = 0 and z = H. So the first point should be on the horizontal axis. At the final position the object is at z = 0 and its p is max, hence it is on the vertical axis. You can use the relation

v^2 = 2g delta(z) to figure out these points. I think that supports the answer.

Though I do not like the apparent hump in the plot.
