Question

Two objects of equal masses move with uniform velocities of 2v and 3v respectively.Find the ratio of their kinetic energies


Pls answer

Answer 1

Hi dear !!!

Masses are same and velocity is 2v and 3v

so KE1 = 1/2m( 2v)²


and KE2 = 1/2 ( 3V )²


so

KE1 / KE2 = 4V² / 9V²

4: 9


hope it help you dear !!!

thanks !!
