PART 3 By using a drag sled, Lt. Henry determined that the coefficient of friction between the tires of Car 2 and the road was 0.60. He could not use the drag sled to determine the coefficient of friction between the tires of Car 1 and the road as it had rolled over the roadway and grass. Think about these questions 10. Did Lt. Henry need to find the coefficient of friction for Car 1? What procedure could he have used to find this information? 11. Using your outlined procedures, find the velocities of the two carsjust prior to the impact. 12. Estimate the coefficient of friction between the rolling tires of Car 1 and the roadway and grass. Be sure to state any assumptions that you make and justify them. 13. During the collision, which car delivered the greater force of impact? Justify your reasoning using physics principles. 14. How did Lt. Henry determine the speeds of both cars just before they applied their brakes? What further information will he need
