Question

State the law of conservation of momentum. Give two illustration in its support.

Answer 1

Answer:

Law of conservation of momentum

It states that the initial momentum is equal to the final momentum

Explanation:

Eg: recoil of a gun

Consider a gun of mass M and bullet of mass m the forward velocity of bullet (muzzle velocity) be v and recoil velocity of gun be V then

Total momentum before shooting=Total momentum after shooting

i. e, MV+mv=M'V'+m'v'
