Question

A rocket is moving up with a velocity v. If the velocity of this rocket is suddenly tripled, what will be
the ratio of two kinetic energies?
(2)​

Answer 1

Answer:

1:9

Explanation:

we know that kinetic energy = 1/2* m*v^2

then, innitial kinetic energy = 1/2 * m*v^2

now, final kinetic energy = 1/2*m*(3v)^2 = 9/2*m*v^2

now ratio will be = (1/2 * m*v^2)/(9/2*m*v^2) = 1:9

hope it helps

Answer 2

Answer:

9:1

Explanation:

This is required solution to the question.
