Question: A gun of mass 20 kg has bullet of mass 0.1 kg in it. The gun is free to recoil 804 J of recoil energy are released on firing the gun. The speed of bullet (ms−1 ) is

(A) \sqrt{804\times 2010}

(B) \sqrt{\dfrac{2010}{804}}

(C) \sqrt{\dfrac{804}{2010}}

(D) \sqrt{804\times 4\times 10^{3}}

Answer: Option (D)

Solution:

A gun of mass 20 kg has bullet of mass 0.1 kg in it. The gun is free to recoil 804 J of recoil energy are released on firing the gun. The speed of bullet (ms−1 ) is
