Question

what will be the percentage change in the momentum of a body when both its mass and velocity are doubled? ​

Answer 1

Answer:

Momentum of a body of given mass, is directly proportiional to its velocity. ... When momentum is doubled, mass remaining constant, this means velcity is doubled. Hence, kinetic energy becomes 22=4 times i.e. say from 100 units to 400 units. and percentage increase in kinetic energy is 400−100=300% .
