a car is traveling at sea level at 78 mi/h on a 4% upgrade before the driver sees a fallen tree in the roadway 150 feet away. the coefficient of road adhesion is 0.8. The car weighs 2700 lbs, has a drag coefficiant of 0.35, a frontal area of 18 ft^2, and a coefficient of rolling friction approximated as .017 for all speed conditions. the car has antilock braking system that gives it a braking efficiancy of 100%. if the driver first applies the brakes 150 ft from the tree, how fast will the car be traveling when it reaches te tree? Include the effect of aerodynamic resistance.
