Question

Two bodies of equal masses move with uniform velocity v and 3V, respectively. Find the ratio of their kinetic energies. ​

Answer 1

Explanation:

v:9v if u cancel both v on either that will alsa b ok.. I it will come as 1:9

Answer 2

Explanation:

Let the first mass be = m

Let the second mass be = M

m = M

v1 = v

v2 = 3V

kinetic energy of first body = ½mv²

kinetic energy of second body = ½m(3v)²

= ½m9v²

therefore the ratio is 1:9
