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 horse and a dog are running with the same velocity- If the mass of horse is ten times the mass of the dog then what will be ratio of their kinetic energy ?

A body is moving with a velocity of 10 m/s. If the motion is uniform, what will be the velocity after 10s?

If mass is doubled and velocity is halved then new kinetic energy is

An insulated container containing monoatomic gas of molar mass m is moving with a velocity V_o . If the container is suddenly stopped, find the change in temperature.

The kinetic energy of an object of mass 'm' moving with a velocity of 5ms^-1 is 25 J. What will be its kinetic energy when its velocity is doubled ? What will be its kinetic energy when its velocity is increased to three times.

A particle with charge q moving with a velocity v in the plane of the paper enters a uniform magnetc field B, acting perpendicular to the plane of the paper. Deduce an expression for the tie period of the charge, as it moves in a circular path in the field. Why does the kinetic energy of the charge not change, while moving in the magnetic field?

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