The braking distance d, in meters, of a vehicle traveling at a velocity v, in meters per second, is given by the formula d = where u 2µg' is the coefficient of friction and g is the acceleration due to gravity. On Earth, gx9.8 m/s. Complete parts (a) and (b) below. (a) Determine the braking distance of a car traveling at 55 km/hr on dry pavement (µ = 0.80). (Be sure to convert the speed to meters per second.) The braking distance is about meters. (Simplify your answer. Round to the nearest integer as needed.) (b) Determine the braking distance of a car traveling at 63 mi/hr on wet pavement (µ = 0.45). Give the final %3D answer in feet. The braking distance is about feet.
