1.	A gun moves backward when a short is fired from it.A shell of mass 0.020 kg is fired by a gun of mass 100 kg. if the muzzle speed of the shell is 80 m/s, what is the recoil speed of the gun?
Answer» Solution :m = 0.020 KG, M = 100 kg, `V = 80 MS^(-1), V- `? `V= mv/M = 0.02xx80/100 = 0.016 ms^(-1)`
