##### Reference no: EM13544751

A cannon with a mass of 115 kg shoots a cannonball with a mass of 8 kg. If the speed of the cannon ball as it leaves the cannon is 185 m/s,what is the speed of the cannon at that time??(assume cannon is initially at rest, not fastened down in any way,and there is no friction between cannon and the ground)
