Question

two objects Aand B having mass 100kg and54kg moving with velocity 54km/hr and 72km/hr respectively. which will have greater momentum ​

Answer 1

Given:-

→Mass of A(m₁)=100kg

→Mass of B(m₂)=54kg

→Velocity of A(v₁)=54km/h

→Velocity of B(v₂)=72km/h

To find:-

•Which object has a greater momentum

Solution:-

Let the momentum of A and B be p₁ and p₂ respectively.

We know that:-

=>p=m×v

Momentum of 'A':-

=>p₁=m₁v₁

=>p₁=100(54)

=>p₁=5400kg m/s

Momentum of 'B':-

=>p₂=m₂v₂

=>p₂=54(72)

=>p₂=3888kg m/s

Since,5400>3888

Thus,p₁>p₂

Hence,object 'A' has a greater momentum.
