Acar is traveling up a 3% grade, with the speed of 85mph, on a road that has good, wet pavement. the radius of the wheels is 15 inches, the driveline slippage is 3%, and the overall gear reduction ratio is 2.5 to 1. a deer jumps out onto the road and the driver applies the brakes 290-ft from it. the driver hits the deer at a speed of 20mph. if the driver did not have antilock brakes, and the wheels were locked the entire distance, would a deer-impact speed of 20mph be possible? (hint: check the braking efficiency) [use theoretical stopping distance]
