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]

A-mn has a cubic structure with a0 0.8931 nm and a density of 7.47 g/cm3. b-mn has a different cubic structure, with a0 0.6326 nm and a density of 7.26 g/cm3. the atomic weight of manganese is 54.938 g/mol and the atomic radius is 0.112 nm. determine the percent volume change that would occur if a-mn transforms to b-mn.
