Abullet with a mass =12.5 g and speed =86.4 m/s is fired into a wooden block with =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 before stopping due to friction between the block and surface. the coefficients of friction are =0.753 and =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)?
