- 18. A bus traveling at 66 ft/sec along a straight, level road decelerates at www w constant rate of 22 ft/sec2 when the brakes are applied. How far does the car travel before coming to complete stop? a.66 ft b. 33 ft C. 11 ft d. 99 ftA motorcycle patrolman starts from rest at A 2 sec. after a car speeding at the constant rate of 120 kph passes point A. If the patrolman accelerates at the rate of 6 m/s2 until he reaches his maximum permissible speed of 150 kph, which he maintains. a. Find the time for the patrolman to reach a maximum permissible speed of 150 kph. b. How long did it take the patrolman to overtake the car from the time he starts from A.? c. Calculate the distance S from point A to the point at which he overtakes the car.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.
- 1. In traveling a distance of 3km between points A and a car is driven at 100kph from A to B for t seconds and at 60kph from C to D also for t seconds. If brakes are applied for 4 seconds between B and C to give the car a uniform deceleration, calculate the t and the distance between A and B. 1/A vehicle is moving along a straight line having an initial speed of 10 m/s. It is experiencing a deceleration of -0.5v2 m/s2 . Determine the distance travelled by the vehicle after three seconds.A train is traveling at 60 km/hr. If its brakes give the train a constant deceleration of O.5 m/s, find the distance from the station where the brakes should be applied so that the train will come to a stop at the station. How long will it take the train to stop?
- Current Attempt in Progress A car is traveling around a circular track of 670-ft radius. If the magnitude of its total acceleration is 6.1 ft/sec² at the instant when its speed is 33 mi/hr, determine the rate at at which the car is changing its speed. Answer: at = ±i eTextbook and Media ft/sec²The brakes of a car are applied, causing it to slow down at a rate of 10 ft/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.2. The acceleration of a tram car starting from rest increase uniformly from 0.6m/sec? to 2.7m/sec2 in 8 sec. Then the car contineus at uniform acceleration for the next 20sec and 11 sec more, is brought to stop with a constant deceleration. Draw the a-t, v-t and s-t.
- Compute the braking distance of a car traveling at 50 kph in a horizontal surface and then brought to rest after the application of the brakes if the average skid resistance is 0.553. 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.A train accelerates uniformly and it passes consecutive mile marks as it travels at velocities of 7 ft/s and then 45 ft/s. Determine the train's velocity when it passes the next mile mark and the time it takes to travel the 2-mile distance.
