The brakes of a car are applied, causing it to slow down at a rate of 10 f/s. Knowing that the car stops in 300 ft, determine (a) how fast the car was traveling immediately before the brakes were applied, (b) the time required for the car to stop.

Q: A car is traveling up a 1.5% grade at 65 mi/hr on good, wet pavement. The driver brakes to try to…

A: Given; Grade: 1.5% (or 0.015 as a decimal) Initial speed: 65 mi/hr Reaction time: 1.5 seconds…

Q: an intersection with speed 45 mph. The road has a downhill grade of 1%. When the car is at a…

A: Using relation for stopping distance SSD=vt+v22gf±Gv=45mph=66ftsG=-1%=-0.01

Q: A driver is traveling 70 mi/hr on a road with a -2% downgrade. The driver's vehicle has a braking…

A: speed V = 70 mi/hr Grade G = -2% braking efficiency = 90% Stopping sight distance = 500 ft lateral…

Q: What is the SSD of a driver/vehicle traveling at 40 mph along a 5% uphill? Assume general braking…

A:

Q: Refer to the following illustration; veh#2 is driving with the speed of 60mph, following veh#1 whose…

A: Speed of vehicle 1, Speed of vehicle 2, Distance, Level grade.To find: Minimum distance between two…

Q: car is traveling up a 3% grade, with the speed of 85mph, on a road that has good, wet pavement. A…

A: Gradient = +3% Initial speed, vo = 85mph = [85 x 1.467] ft/sec Total distance covered in brake…
