Question

What will be the ratio of its initial and final kinetic energy, if the mass of
the body is tripled and its velocity is halved? ​

Answer 1

Answer:

the answer is 2/3

Explanation:

kE¹/kE² then put the value of final mass and velocity then you will get your answer❤

Answer 2

hey dude....it depends on simple mathematical caculation....

as we know k=1/2 mv^2

let initial =1/2mv^2

then final=1/2 ×3m×v^2/4

=3mv^2/8

taking their ratio we get:3/4

hope it helps
