Answer:
(a) The kinetic energy of the object is directly proportional to the mass, therefore on doubling the mass kinetic energy will also become double.
(b) If velocity is doubled, Kinetic Energy increases by 4 times. Kinetic energy of a body is the energy possessed by it, by virtue of its motion, i.e. if the body is moving it will always have kinetic energy.
