For a given motor vehicle, the maximum achievable deceleration from braking is approximately 7 1/s² on dry concrete. On wet asphalt, it is approximately 2.5 m/s². Note that 1 mi/hr corresponds to 0.447 m/s. Round answers to to the nearest whole number. m Find the total distance that a car travels in meters on dry concrete after the brakes are applied until it comes to a complete stop if the initial velocity is 67 mi/hr. m Find the corresponding distance if the surface is slippery wet asphalt. m For a given motor vehicle, the maximum achievable deceleration from braking is approximately 7 1/s² on dry concrete.
