- 5) A car is traveling along a straight road with an acceleration of a = 1/4 * s ^ (1/4) (m/s^ 2 ) Determine the velocity when the car travels 2 (m).An automobile starting from rest speeds up to 40 meters per seconds with a constant acceleration of 4 meter per seconds square, runs at this speed for a time, and finally comes to rest with a deceleration of 5 meters per second square. If the total distance traveled is 1000 meters, find the (a) distance traveled covered during the acceleration, (b) distance traveled at constand speed, and (c) the total time of travel.3. Two cars A and B travelling in the same direction and stopped at a highway traffic sign. As the signal turns green car A accelerates at a constant rate of 1m/s2. Two seconds later the second car B accelerates at constant rate of 1.3m/s2. When will the second car B overtakes the first car A.
- You are to determine the duration of the yellow light at a highway intersection. Assume that cars will be approaching the intersection traveling at 70 mph, and that the reaction time of the driver is 2.5 sec and that cars achieve a deceleration of 1/8 of the gravitational acceleration. if g=32.2 fps^2, a. how long must the traffic light remain yellow to allow drivers to come to stop before the traffic light turns red? b. what is the minimum distance of a car from the intersection when the lightturns yellow to ensure that it comes to a full stop before the intersection?While travelling at a constant speed a driver saw a road block 112 m away. He applied the brakes and the car decelerated uniformly at 6.4 m/s^2. It stopped 5 m from the block. Find the initial constant speed of the vehicles in kph, if the drivers perception reaction is 2.2 second. a. 91.86 b. 26.31 c. 25.52 d. 94.72An automobile A travelling at a constant velocity of 45 ft/s passes a gasoline station. After 2 seconds, another automobile B leaves the gasoline station and accelerates at the constant rate of 6 ft/s2. How long will the second automobile overtakes the first?
- John starts on a walk from his house at 9 AM. He reaches his destination 4.5 km away from his house at 10:00 AM. What was John’s average speed? A. 0.5 kph B. 0.43 kph C. 3 kph D. 4.5 kphIn traveling a distance of 3 km between points A and D, a car is driven at 100 km/hr from A to B for t seconds. If the brakes are applied for 4 sec between B and C to give a car uniform deceleration from 100 kmph to 60 kmph and it takes ' t ' seconds to move from C to D with a uniform speed of 60 kmph, determine the value of ' t '.Two cars A and B are stopped at a traffic light, waiting for the light to change from red to green, see Figure 3. Car B is 6 meters behind car A. When the light turns green, car A starts accelerating at a rate of 0.3 m / sec2, while car B departs 2 seconds later and accelerates at a rate of 0.8 m / sec2. Determine the speed each car was carrying when they are side by side.
- You are riding home from a party and the driver is drunk. The car is traveling at 60 mi/hr. Suddenly, a child steps into the road ahead. Since the driver is drunk his reaction time has been slowed by 1s. How far will the car travel before the driver begins to stop? (This is equal to the distance it will take to stop the car because the driver is drunk.)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?it takes about 3 s for a driver having 0.1% alcohol in his system to react to a situation to avoid a collision. if such drivers are traveling on a straight road at 40.11ft/s and their cars can decelerate at 2.714ft/s^2, determine the shortest stopping distance d (in feet) from the moment they see the pedestrians.
