    block stricked by a bullet
    A block of wood with mass = 4.65 kg is resting on a horizontal surface when a bullet with mass of 18g and moving with a speed of 725m/s strikes it. The coefficient of friction between the block and the surface is 0.35. The distance the block moves across the surface is?
