A rocket is moving up with a velocity `upsilon` if the velocity of this rocket is suddenly tripled, what will be the ratio of two kinetic energies ?

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?

A rocket is moving in upward direction with the velocity v, suddenly its velocity becomes three times, then find the ratio of its initial and final kinetic energy.

Two sopheres whose radii are in the ratio 1:2 are moving with theier velocities in the ratio 3:4. If their densities are in the ratio 3:2, the ratio of their kinetic energies is

Two bodies of equal masses move with uniform velocities upsilon and 3 upsilon respectively. Find the ratio of their kinetic energies.
