2ug*
is the coefficient of friction and g is the acceleration due to gravity. On Earth,
where
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 (u = 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 (u = 0.45). Give the final
answer in feet.
The braking distance is about
feet.
(Round to the nearest ten as needed.)
