A ball is through vertically up (taken as +z-axis) from the ground. The correct momentum-height (p-h) diagram is :

Options

A.
B.
C.
D.

Answer

C

Explanation

`V^2 = u^2 - 2gh " " implies " "m^2v^2 = m^2u^2 - 2mgh implies p^2 = A - Bh ` (Where `A = m^2u^2 , b = 2mg)`
Clearly it is parabolic functions.
Starting from ground momentum first decreases and then becomes zero at highest position. Therefore it increases in –ve direction. Hence `3^(rd)` option is correct.
