Question

Two bodies of masses m and 2m have equal kinetic energies. The ratio of their linear momentum is​

Answer 1

Answer:

ratio = 1 : 2

Explanation:

let the kinetic energy be 'x'.

linear momentum of body having mass m = mx

linear momentum of body having mass 2m = 2mx

ratio of their linear momentum = mx / 2mx

by cancelling the common factor 'mx' ,

ratio = 1 / 2 = 1 : 2

Answer 2

ratio = 1 : 2

let the kinetic energy be 'x'.

linear momentum of body having mass m = mx

linear momentum of body having mass 2m = 2mx

ratio of their linear momentum = mx / 2mx

by cancelling the common factor 'mx' ,

ratio = 1 / 2 = 1 : 2
