Question

5 kg gun fires a bullet of 15 grams at a velocity of 1000 metre per second to the right what is the velocity of the recoil of the gun please give me a step-by-step solution I have aked many times but nobody is given a step-by-step solution if anybody will give me step-by-step solution I will mark in brainly plzz answer I will mark them brainliest​ . 9 Std Maharashtra state board​

Answer 1

Answer:

given, bullet mass=15 g

gun mass=5kg

velocity=1000m/s

now,

mass of bullet=15g

=15/1000kg

=.015kg

velocity of bullet =1000m/s

mass of gun =5 kg

(to calculate recoil velocity of gun __

(mass of bullet × velocity of bullet)

=(mass of gun ×recoil velocity of gun)

=(0.015×1000)=(5×recoil velocity of gun)

=recoil velocity=.015×1000/5

=3 m/s (answer is 3m/s)

hopes it helps u!!.plzz mark it as brainliest

(the above problem can also be solved by calculating the momentum of bullet and gun separately : (showing another way to solve)

momentum of bullet=mass of bullet

×velocity of bullet

=0.015×1000

=15kg.m/s

now,let recoil velocity of gun be v m/s

= momentum of gun = mass of gun × recoil velocity of gun

15=5×v

v=15/5

v=3 m/s

answer is same method is different ..mark it as a brainliest
