Question

Question 8. Ek 145 kg ka shell 15 ton mass wale gun se fire kiya jata hai jiska muzzle velocity
450 meter per second hai. Batao ki gun ka recoil velocity kitna hoga. Agar recoil ko 1 meter per
spring ke madad se roka jaye to average force spring par kya hoga.​

Answer 1

P1=145×450=65250 kgm/s

P2=15000×v

By law of conservation of momentum

P1=P2

15000v=65250

V=261/60 m/s

Recoil velocity =261/60 m/s
