Homework Statement
A person is standing on a sheet of ice so slippery that friction may be ignored. This individual fires a gun parallel to the ground. When a standard cartridge is used , a 13-g bullet is shot forward with a speed of 290 m/s, and the person recoils with a speed of vc. When a blank cartridge is used , a mass of 0.13g is shot forward with a speed of 53 m/s , and the recoil speed is vb. Find the ratio vb/vc.
Homework Equations
I tried to use P= p1+p2
I got
P1=13*Vc
P2=.13*Vb
Ended with 13Vc+.13Vb
I am sooo confused. Its asking for the ratio and its totally throwing me off. Plus I am not even sure I am using the right formula or if I understand the question properly
