Problem
A bullet with a mass of 5.0 g is fired horizontally into a 2.0 kg wooden block which is resting on a horizontal table. The bullet stops in the block and the block and bullet combination move 2.0 m. The coefficient of kinetic friction between the block and surface of the table is 0.2. Find the initial speed of the bullet.
a. 1123 m/s b. 1134 m/s c. 1132 m/s d. 113.2 m/s e. 113.4 m/s
