Question
You are working on a crime scene investigation where a victim has been shot at point blank range. Athe the point of entry, the bullet struck a small bone. An 8.2g piece of the bone stuck to the 22g bullet and the two were deflected by an angle of 12 deggres from the line of entry. The rest of the bone, 16.8g, was deflected at an angle of 23 degrees from the line of entry. You can tell by how far the 16.8g piece of bone travelled that it must have had a velocity of 470 m/s the instant after the bullet struck the bone.
a) What was the speed of the bullet and bone chip after the collision (v'1)?
b) What was the speed of the bullet before the collision (v)? (use the velocity found in part a)
