A body moving with velocity `v` has momentum and kinetic energy mumerically equal. What is the value of `v`?

If a body of mass m is moving with velocity v then prove that kinetic energy of the body = frac(1)(2) mv^2

(a) A body of mass m is moving with a velocity v. Write the expression for its kinetic energy. (b) Show that the quantity 2K/v^(2) has the unit of mass, where K is the kinetic energy of the body.

An impulse I given to a body changes its velocity from v to 3v .The increase in kinetic energy of the body is given by ?

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?

If the momentum of a body moving with constant velocity is four times its kinetic energy, its velocity is
