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?

What type of bullet, was there penetration into the block. What was the size and shape of the bullet tip.

I will guess and assume you are doing homework that is not "real life" questions, and in reality not 100 percent correct as done in science for forensic study.
