## 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 14-g bullet is shot forward with a speed of 270 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

vb/vc

## The Attempt at a Solution

i simply tried mass(velocity) for each one and did vb/vc to get .0018 but the answer is not right. I'm not sure if i have an error or if those are the wrong steps
