Question

a cannon of mass m1=1000kg located on asmooth horizontal (platform) fires a shell of mass m2=300kg in horizontal direction with a velocity v2=400 m/s .find tge velocity of the canon after it is shoot​

Answer 1

Answer:

Formula: V = -mv/M

, where m is the mass of shell and M is the mass of cannon and v is the velocity of shell and V is the cannon.

V = -300*400/1000 m/s

V = -120000/1000 m/s

V = -120 m/s

It is negative because the direction of movement of cannon is opposite to that of the fired shell.

I hope this helps.
