A 9.0-g bullet is fired into a 160-g block of wood at rest on a horizontal surface. After impact, the block slides 7.80 m before coming to rest. If the coefficient of friction between the block and the surface is 0.430, what is the speed of the bullet before impact?

    A 98.0 g wooden block is initially at rest on a rough horizontal surface when a 12.2 g bullet is fired horizontally into (but does not go through) it. After the impact, the block–bullet combination slides 6.5 m before coming to rest. If the coefficient of kinetic friction between block and surface is 0.750, determine the speed of the bullet (in m/s) immediately before impact.
