A bullet with a mass m = 12.5 g and speed v = 97.4 m/s is fired into a wooden block with M = 113 g which is initially at rest on a horizontal surface. The bullet is embedded into the block. The block-bullet combination slides across the surface for a distance d before stopping due to friction between the block and surface. The coefficients of friction are A?µs = 0.753 and A?µk = 0.659. (a) What is the speed (m/s) of the block-bullet combination immediately after the collision? (b) What is the distance d (m)?
