1) Calculate the ratio of momentum, when

Velocity of an object is doubled

Mass of an object is halved

Both mass and velocity are increased by three times

Momentum = mvwhere m is mass and v is velocityp = mv(1) when velocity becomes doublep1 = m(2v) = 2mv = 2p(2) when mass of object is halvedp2 = mv2= p2(3) When mass and velocity are increased by three timesp3 = 3m×3v = 9mv = 9pp1:p2:p3 = 2p : p2: 9p= 4:1:18
