Question

A bullet of mass 10 gram is fired from a gun of mass 6 kg with velocity of 300m/s. Calculate the recoll velocity of gun

Answer 1

conversation of momentum
M1V1=M2V2
M1=mass of bullet in kg=10/1000=1/100kg
V1 =velocity of bullet=300m/s
M2=mass of gun=6kg
V2=velocity of gun
1/100×300=6×V1
3=6×V1
V1=3/6
V1=0.5m/s

Answer 2

Answer:

0.5m/s

Explanation:

mass of bullet in kg= 10/1000=0.01 kg

gun of mass= 6kg

velocity of bullet= 300m/s

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

0.01×300=6×velocity of gun

1/100×300=6× velocity of gun

velocity of gun=3/6=1/2=0.5 m/s.
