Question

A bullet of mass 100g is fired from a
gun of mass 20kg with a velocity of
100m/s . calculate the velocity of recoil of the gun​

Answer 1

Explanation:

m(urel-v) = M(v)

100/1000(100-v) = 20(v)

100 - v = 200v

v = 100/200

v = 0.497 m/sec

Answer 2

Answer:

=200

Explanation:

100kg+100kg-20kg=200
