Answer:
If momentum of an object is doubled, then what is the change in ... 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 velocity is doubled. Hence, kinetic energy becomes 22=4 times i.e. say from 100 units to 400 units
