4. A car comes to a complete stop from an initial speed of 50 mi/hr in a distance of 100 ft. With the
same constant acceleration, what would be the stopping distance s from an initial speed of 70
mi/hr?
Four race cars are traveling on a 2.5-mile tri-oval track. The four cars are traveling at constant speeds of 195 mph, 190 mph, 185 mph, and 180 mph respectively. Assume you are an observer standing at a point on the track for a period of 30 minutes and are recording the instantaneous speed of each vehicle as it crosses your point.
Find the TSM, SMS, q, and k
Car 1 is at gasoline station for 10 minutes. The driver notices that car 2 passes at a speed of 40 mph. How long will it take for Car 1 to overtake Car 2 if it accelerated at 4 m/s?

- A train which is traveling at 80 mi/h applies its brakes as it reaches point A and slows down with a constant deceleration. Its decreased velocity is observed to be 60 mi/h as it passes a point 1/2 mi beyond A. A car moving at 50 mi/h passes point B at the same instant that the train reaches point A. In an unwise effort to beat the train to the crossing, the driver "steps on the gas." Calculate the constant acceleration "a" that the car must have in order to beat the train to the crossing by 4 sec and find the velocity "v" of the car as it reaches the crossing.

An observer located at point X observes the four vehicles passing point X during a period of 10 seconds. The speeds of the vehicles are measured as 45, 45, 40, and 30mph, respectively. Calculate the average flow, density, time mean speed, and space mean speed.arrow_forwardThe car decelerated at a rate of 10 ft/s^2 after the brakes are applied and stops at 300 ft from its initial position. What is the initial velocity of the car as it was traveling before the brakes were applied? How much time it takes the car to stop?arrow_forward
- Five minivans and three trucks are traveling on a 1.5 mile circular track and complete a full lap in 90.0, 100.0, 102.0, 80.0, 90.0, 101.0, 85.0, and 95 seconds, respectively. Assuming all the vehicles are traveling at constant speeds: (a) what is the time-mean speed and space-mean speed of the minivans? (b) what is the time-mean speed and space mean speed of all vehicles?arrow_forwardA car is traveling around a circular track of 820-ft radius. If the magnitude of its total acceleration is 6.7 ft/sec? at the instant when its speed is 37 mi/hr, determine the rate a, at which the car is changing its speed.arrow_forwardCar A is traveling at a constant speed vA = 125 km/h at a location where the speed limit is 100 km/h. The police officer in car P observes this speed via radar. At the moment when A passes P, the police car begins to accelerate at the constant rate of 4.0 m/s? until a speed of 168 km/h is achieved, and that speed is then maintained.

- 2. A Hyundai Santa Fe travels a 1.30km levelled road from Bonifacio roundabout to City Lights Hotel in a minimum time of 45.60seconds. Given that the car accelerates and decelerates at 2.53 m/s², which starts from rest at the roundabout and coming to a stop at the Hotel, determine the maximum speed (in kph) and the time (in seconds) it travel at this speed. Assume time for acceleration and deceleration are equal.arrow_forwardYou are designing an on-ramp that connects an intersection (controlled by a signal) and the highway. You want to assure that vehicles that are completely stopped at the intersection can reach the prevalent highway speed, which is assumed to be 60mph. Assume that passengers have the maximum acceleration rate of 10 ft/sec2 , trucks have smaller acceleration rate 3.2 ft/sec2 . You can assume that vehicles can use the maximum acceleration rate regardless of the speed. What’s the reasonable length for the ramp?arrow_forwardThe length of a highway is 550 m when a head-on vehicle collision occurred. Police reports show that neither human error nor vehicle malfunction was the cause of the collision. Check if the length of the highway is sufficient for an overtaking maneuver. Accident Report: -Speed of Overtaking Car = 96 kph -Speed of Overtaken Car= 88 kph -Perception-reaction time = 2.5 sec -Average acceleration = 2.4 m/sec? -Time of the passing vehicle occupying the left lane (10.4 sec) - Distance between the passing vehicle at the end of its maneuver and the opposing vehicle= 84 marrow_forward

The driver of car A is traveling at và = 122 km/h as it passes P, but over the next 4.1 seconds, the car uniformly decelerates to the speed limit of 100 km/h, and after that the speed limit is maintained. At the moment when A passes P, the police car begins to accelerate at the constant rate of 4.0 m/s² until a speed of 164 km/h is achieved, and that speed is then maintained.
