Question

a gun of mass 3000kg fires as shell of mass 5 kg in horizontal direction the gun recles at 0.4 ms calculate the velocity of shell​

Answer 1

Answer:

given,

mass of gun m1 =3000kg

velocity of gun v1=0.4m/s

mass of shell m2 =5kg

find,

velocity of shell v2 =?

formula

m1v1=m2v2

v2=m1v1/m2

= 3000×0.4/5

=1200/5

=240m/s
