Question

A car starts from rest, then accelerates at a constant rate over a distance of 89 m. It then immediately decelerates at a constant rate over a distance of 152 m. The entire trip lasts a total duration of 27.2 s. What were the magnitudes of the car s accelerations for the speedup and slowdown stages respectively?

1.    1.76 m/s^2, then 1.03 m/s^2
2.    3.27 m/s^2, then 5.59 m/s^2
3.    0.65 m/s^2, then 0.65 m/s^2
4.    5.59 m/s^2, then 3.27 m/s^2
Expert Solution
Step 1

Given value---

  • first covered distance = 89 m.
  • second cover distance ÷ 152 m.
  • total taken time = 27.2 seconds. 

We have to find---

  • What were the magnitudes of the car s accelerations for the speedup and slowdown stages respectively?
