Question

Ek 145 kg ka shell 15 ton mass wale gun se fire kiya jata hain jiska muzzel velocity 450m/s2 hai batao ki reloil velocity kitna hoga? agar recoil ko 1 mtr per soring ke madad se roka jaye to avarage force spring per kya hoga

Answer 1

Answer:

Explanation: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
