Question

12. A gun weighs 5kg. A bullet of mass 8g when fired, leave the gun with 400mis velocity. Find velocity of recoil of the gun​

Answer 1

Answer:

0.65 will be the valocity

Explanation:

Answer 2

Answer:

0.64 m/s

Explanation:

by the 3rd law of motion

energy conserves

so

mass ×velocity of bullet =mass of gun × velocity of gun

8/1000 kg ×400 m/s=5kg×velocity (changing 8 gm to kg)

by solving

32/10=5× velocity

velocity =0.64 m/s
