Maria was trying to test the braking ability of her car determined that she needed 5.64m more to stop her car when driving downhill on a road segment of 5% grade than when driving downhill at the same speed along another segment of 3% grade. Determine the speed at which the student conducted her test and the braking distance on the 5% grade if the student is travelling at the test speed in the uphill direction.

A car is approaching toward an intersection with speed 45 mph. The road has a downhill grade of 1%. When the car is at a distance of 250 ft from the intersection, the signal turned yellow. If the driver applies brake and the reaction time of the driver is 1.5 s, will the driver be able to come to a complete stop? Justify your answer with calculations. Assume braking friction coefficient of 0.35.
A student trying to test the braking ability of her car determined that she needed 19.5 ft more to stop her car when driving downhill on a road segment of 5% grade than when driving downhill at the same speed along another segment of 3.5% grade. Determine the speed at which the student conducted her test and the braking distance on the 5% grade if the student is traveling at the test speed in the uphill direction.

1. A car is approachin an intersection with velocity 35 mph. When the car is at a distance of 200 ft from the intersection, the signal turned yellow. If the driver decides to break, will he be able to stop safely? The driver's reaction time is 1.5 s. Assume the road surface as leveled. The maximum braking effort is applied. Will your answer change, if the grade of the road surface is downhill 3%? A car is at a distance of 200 ft from an intersection stop line when the signal turned yellow. What should be the minimum speed of the car (miles/hour) if the driver decides to apply brake and is just able to stop at the line? Use reaction time of 1.5 s and the road surface has zero grade.
a truck was travelling uphill at 50kph. the brakes are suddenly applied and the truck stopped in a distance of 16.1m. if the coefficient of friction between the tires and the road surface is 0.4, what is the grade of the road?
Problem 2. A car hits a tree at an estimated speed of 25 mph on a 3 % upgrade. If skid marks of 120 ft are observed on dry pavement (coefficient of braking friction, fb =0.35) followed by 250 ft (fb =0.25) on a grass stabilized shoulder, estimate the initial speed of the vehicle just before the pavement skid began.
A student trying to test the braking ability of his car, determined that he needed 32 ft. More to stop his car downhill on a particular road than uphill when driving at 55 mph. Assuming that the coefficient of friction between the tires and the pavement is 0.30. Determine the braking distance downhill and the percent grade of the highway at that section of the road.
A motorist travelling at 100 km/hr on a highway needs to take the next exit, which has a speed limit of 50 km/hr. The section of the roadway before the ramp entry has a downgrade of 3% and coefficient of friction (f) is 0.35. In order to enter the ramp at the maximum allowable speed limit, determine the braking distance (expressed in m) from the exit ramp.
A rear-wheel-drive 2800-lb drag race car has a 170-inch wheelbase and a center of gravity 20 inches above the pavement and 140 inches behind the front axle. The owners wish to achieve an initial acceleration from rest of 22 ft/s 2 on a level paved surface. What is the minimum coefficient of road adhesion (in %) needed to achieve this acceleration? (Assume y m = 1.00.)
A car is traveling up a 1.5% grade at 65 mi/hr on good, wet pavement. The driver brakes to try to avoid hitting a cone on the road that is 300 ft ahead. The driver's reaction time is 1.5 second. When the driver first applies the brakes, a software flaw causes the braking efficiency to lower to 0.8 for 100 ft. After the initial 100 ft, the braking efficiency returns to 1.0. How fast will the driver be going when the cone on the road is hit if the coefficient of rolling resistance is constant at 0.015? (Assume minimum theoretical stopping distance and ignore aerodynamic resistance.)
A car is traveling at 76 mi/hr down a 3% grade on poor, wet pavement. The car's braking efficiency is 90%. The brakes were applied 320 ft before impacting an object. The car had an antilock braking system, but the system failed 200ft after the brakes had been applied (wheels locked). What speed was the car traveling at just before it impacted the object? (Assume theoretical stopping distance, ignore air resistance, and let Frl=0.015)
