A bullet with mass 12.5 g and speed 94.9 m/s is fired into a wooden block with a mass of 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 thh block and surface. The coefficients of friction are us=.753 and uk=.659.
a. What is the speed of the block-bullet system immediately after collision?
b. What is the distance in m?
