Question

Hi, 

 

Heres another problem.

 

If the driver slows down the speed evenly v₁= 71km/h to v₂=54km/h using 0,20 min to this

 

Also how to calculate the cars acceleration? (m/s²)  and how long the car went during this time?

Answer 1

Since the question was worded a bit off, it is difficult to create a proper lesson. 

However, these questions can be written from many angles. I recommend reviewing a related lesson on the related topic so that you can get a grasp on the different concepts, and then you should be able to figure your question or post it as it was written originally.

Good luck this semester! Here is a a related lesson youtu. be/3t4eug8ARcs?si=5Jxo5OwLyMDmsHOg
