- ASAP. THANK YOU! A man drives at a rate of 25 kph towards the foot of an 8-m tall monument. At what rate is he approaching the top when he is 42m from the foot of the monument? A. 21.45 kph B. 31.58 kph C. 24.56 kph D. 6.82 kphAn 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.In traveling a distance of 3.3 km between points A and D, a car is driven at 86 km/h from A to B for t seconds and 42 km/h from C to D also for t seconds. If the brakes are applied for 4.8 seconds between B and C to give the car a uniform deceleration, calculate t and the distance s between A and B.
- 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).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.In 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 '.
- The brakes of a car are applied, causing it to slow down at a rate of 10 ft/s2. Knowing that the car stops 300 ft, determine (a) how fast the car was traveling immediately before brakes were applied, (b) the time required for the car to stop.Calculate the setback distance on a national highway having horizontal curve of radius 300 m and length of 180 m. Assume speed of 80 km/h and coefficient of friction of 0.35 and perception-reactions time of 2.5 seconds.A car starts from rest and travels 10 sec. with an acceleration of a = 4 – 0.3t, then runs for 30 sec. at constant velocity and finally comes to rest by decelerating at 3.125 m/s2. Determine the velocity of the car after 10 sec. Determine the distance traveled by the car during the period of 10 sec. c. Determine the total distance traveled by the car until it stops.
- Jaylen was driving a vehicle in Anaheim where he got distracted by a group of cute students of a school until he noticed the stoplight just about 15 meters ahead. How much deceleration should he need in meters per second per second if he is at a velocity of 60 kph and he needs to stop at the stoplight?the dragster starts from rest and has a velocity described by the graph. determine the total distance traveled in meters during time interval 0< t<15 s.A motorcyclist at A is traveling at 60 ft/s when he wishes to pass the truck T which is traveling at a constant speed of 60 ft/s. To do so the motorcyclist accelerates at a = 6 ft/s^2 until reaching a maximum speed of 85 ft/s If he then maintains this speed, determine the time needed for him to reach a point located 100 ft in front of the truck. Draw the v-t and s-t graphs for the motorcycle during this time.
