Question

Two objects moving with same velocity of 30 m/s and mass of 1st is 20kg and other one is 30 kg. What is different between both momentums.

Answer 1

In the first case , Velocity = v = 30 m/s and mass = m1 = 20 kg. Therefore,  momentum, p1 = m1 × v =  20 × 30 kg m/s = 600 kg m/s.  In the second case ,  Velocity = v = 30 m/s and mass = m2 = 30 kg. Therefore,  momentum,  p2 = m2 ×v = 30 × 30 kg m/s = 900 kg m/s. Hence the difference between both the momentum is that the momentum of the second object is greater than the first by 300 kg m/s.
