PROCEDURE 1. Use the ruler to measure the minor and major axes of the bullet hole (Figure 7, next page). Record the measurements in Table 1. 2. Use the equation sin e = minor axis (mm)/major axis (mm) to determine the angle at which the bullet impacted the wall. Record the angle in Table 1. J3. Use a tape measure and masking tape to hang Figure 7 on a wall so that the bullet hole is located 80" from the floor. 4. Use the masking tape, string, and angle of impact to create a trajectory from the bullet hole to the ground. 5. As your investigation proceeds, a latent shoe print is recovered 45" from the wall with the bullet hole facing the wall. 6. Draw a diagram of the wall, floor, and bullet trajectory. 7. Use trigonometry to calculate the approximate shoulder height of the shooter. Record the approximate shoulder height in Table 1. 8. Check your work by using the measuring tape to determine if the calculated shoulder height falls on the estimated trajectory of the bullet.
