Question
Two bodies A and B of masses m and M (M ≫ m) have same kinetic energy. Which body will have more momentum?
Solution
Kinetic energy is related to momentum and mass as
p = `sqrt (2 "mk")`
As the kinetic energy of both bodies are same, momentum is directly proportional to square root of mass.
Now, mass of body B is greater than that of body A.
Hence, body B will have more momentum than body A.
