A driver travelling at 50mph sees a hazard at a certain distance ahead. The driver then applies the brakes immediately, time is 2sec and begins slowing the vehicle at 10m/s^2. If the distance from the stopping point to avoid hitting the boulder is 10.28m, how far the car from the hazard upon perception.

A driver driving at 69 kph at a straight flat portion of the highway suddenly encounters an obstruction. He applies his brakes. If the coefficient of friction of the roadway to the tires is equal to 0.5, calculate the maximum safe distance (rounded to the nearest meters) the driver can apply his brakes to avoid collision. g = 9.81 m/s^2

A motorist is traveling at v0 = 64 km/h when she observes that a traffic light x = 327m ahead of her turns red. The traffic light is timed to stay red for 27s. If the motorist wishes to pass the light without stopping just as it turns green again, determine (a) the required uniform deceleration of the car and (b) the speed of the car as it passes the light.
a driver is traveling at 65 mi/h rounds a curve on a level grade to see a truck overturned across the roadway at a distance of 350 ft. if the drivers is able to decelerate at a rate of 10 ft/s2. At what speed will the vehicle hit the truck? Plot the result for reaction times ranging from 0.5 to 5 seconds in increments of 0.5 seconds
