Answer:
In fact momentum is mass multiplied by velocity. Kinetic energy of a body of given mass, is directly proportiional to its square of its velocity. When momentum is doubled, mass remaining constant, this means velcity is doubled. ... and percentage increase in kinetic energy is 400−100=300% .
correct answer is the option 300%.
