Abullet 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 µs = 0.753 and 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)?
