Question

pls answer me in detail​

Answer 1

Mass of bullet = 100g = 0.1kg

Velocity =100m/s

Momentum =mv = 0.1×100 = 10kgms-¹

According to law of conservation of momentum, the momentum remains conserved after the collision.

So, Now,

Velocity with which ethe gun recoiled = 10m/s

So,

p = p¹

10 = 10m

m = 1

So,The mass of gun is (A)1kg
