An automobile accelerates from rest at 2.01 m/s2 for 19.5 s. The speed is then held constant for 19.5 s, after which there is an acceleraton of -3.20 m/s2 until the automobile stops. What is the total distance traveled?
An auto accelerates from rest with acceleration a = 5 m/s2 for 10 s. It then maintains constant velocity for a period of time. Finally, in phase 3, it accelerates uniformly to rest over a period of 20 s. It travels a total distance of 1000 m. How much time does it spend traveling at constant speed? The answer is 5 s but I don't know how to get it. Show all work thanks!
Prob. 2 A car starts from rest, accelerates at 1.5 m/s, and reaches a maximum speed vi. After that it decelerates at 2 m/s until it stops. During the entire process the car has traveled a distance of I km. (a) Sketch the velocity diagram of the particle during the process. (Leave vI as an unknown on the diagram) (b) Determine the maximum speed vi. (e) Determine the total time required.
An electric vehicle starts from rest and accelerates at a rate of 2 m/s2 in a straight line until it reaches a speed of 20 m/s. The vehicle then slows at a constant rate of 1 m/s2 until it stops. (a) How much time elapses from start to stop? (b) How far does the vehicle travel from start to stop?
A train accelerates at 6.52 m/s 2 from rest to a steady speed of 38.41 m/s. It maintains that speed for 1.05 miles and then starts slowing down at 2.21 m/s 2 until coming to a stop at its destination. What is the total distance traveled?
