A car starts from rest, then accelerates at a constant rate over a distance of 54 m. It then immediately decelerates at a constant rate over a distance of 103 m. The entire trip lasts a total duration of 12.7 s. What were the magnitudes of the car s accelerations for the speedup and slowdown stages respectively?
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.
