You have been called to testify as an expert witness in a trial involving a head-on collision. Car A weighs 1515 lb and was raveling eastward. Car B weighs 1125 lb and was traveling westward at 43.0 mph. The cars locked bumpers and slid eastward with their wheels locked for 22.5 ft before stopping. You have measured the coefficient of kinetic friction between the tires and he pavement to be 0.750. What speed v (in miles per hour) was car A traveling just before the collision? (This problem uses English units V= mph

### Expert Testimony in Physics: Head-on Collision Analysis You have been called to testify as an expert witness in a trial involving a head-on collision. Car A: - Weight: 1515 lb - Traveling direction: Eastward Car B: - Weight: 1125 lb - Traveling direction: Westward at 43.0 mph **Collision Details:** - After the collision, the cars locked bumpers and skidded eastward with wheels locked for 22.5 ft before coming to a halt. - The coefficient of kinetic friction between the tires and the pavement is 0.750. **Question:** Determine the speed \( v \) (in miles per hour) at which Car A was traveling just before the collision. This problem applies English units as they would be used in a U.S. legal proceeding. **Calculation Placeholder:** \( v = \) [ ] mph
