Step-by-step explanation:
Answer:
4m/s
Explanation:
Given:
m1 = 40g = 0.04 kg
m2 = 8 kg
v1 = 800 m/s
To find:
v2 = ?
Fomula :
m1v1 = m2v2
Solution:
According to law of conservation of momentum
m1v1 = m2v2
= 0.04 × 800 = 8 × v2
= v2 = 0.04 × 800/8
v2 = 0.04 × 100
v2 = 4
v2 = 4m/s
Therefore, the recoil velocity of the gun is 4m/s.
Hope this helps you buddy!!!
