# A rifle bullet with a mass of \( 12.0 \) \( \text{g} \) traveling toward the right at \( 260 \) \( \text{m/s} \) strikes a large bag of sand and penetrates to a depth of \( 23.0 \) \( \text{cm} \). Determine the magnitude and direction of the friction force (assumed constant) that acts on the bullet.
