Which of the following graphs represents the graphical relation between momentum (p) and kinetic energy (K) for a body in motion?

Options

A.
B.
C.
D.

Answer

D

Explanation

`P_(2) = (11)/(10) p_(1) `
`therefore v_(2) = (11)/(10) v_(1)`
Also, `E prop v^(2)`
`therefore E_(2 = (121)/(100) E_(1)`
`Delta E% = (E_(2) - E_(1))/(E_(1)) xx 100 `
= `((121)/(100) - 1) xx 100 = 21 % `
