A physics student flips out when he keeps missing the same question on a Concept Builder. Outraged by the futility of his efforts, he flings his .05 kg mechanical pencil across the room. The pencil lodges into a 0.221 kg Sponge Bob doll that is at rest on a countertop. Once in motion, the pencil/doll combination slide a distance of 0.119 m across the countertop before stopping. The coefficient of friction between the doll and the countertop is 0.325. (use g=9.8 m/s/s)
