Problem
A 10 g bullet embeds itself in the center of a 1.5 kg wooden block that is initially at rest on a rough horizontal table. After the collision, the bullet–block combination slides 0.80 m before coming to rest. The coefficient of kinetic friction between the block and the table is 0.30.
Determine the initial speed of the bullet just before impact. Express your answer to two significant figures.
