Acar accelerates from rest to a velocity of 5 meters/second in 4 seconds. what is its average acceleration over this period of time?

In this question, due importance should be given to all the information's that are provided in the question. Based on those information's the answer to the question can be easily deduced. Let us first write down all the provided information's.
Initial Velocity (V1) = 0 m/s
Final Velocity (V2) = 5 m/s
Initial time (T1) = 0 sec
Final Time (T2) = 4 sec
Then
Average acceleration of the car = (V2 -V1)/(T2 - T1)
                                                   = (5 - 0)/(4 - 0) m/s^2
                                                   = 5/4 m/s^2
                                                   1.25 m/s^2
So the average acceleration of the car over this period of time is 1.25 m/s^2. I hope the process is clear for you to understand.

|Average acceleration| = (change in speed) / (time for the change)

Change in speed = (speed at the end) - (speed at the start)

|Average acceleration| = (5 m/s - 0) / (4 sec)

                                       =   (5 / 4)  m/s²

                                       =      1.25 m/s²  .

the following is queen elizabeth’s purposes:

- to encourage the parliament that the technique of picking successors to the seat based merely on birthright needs to be reviewed.

- (not) to convince the parliament that her kid should not be measured as a likely choice for heir to the english power.

- to persuade the parliament that merely since she has a child does not assure that the kid will be a capable leader.

- to sway the parliament how shattering it could be if they proceeded discourteously concerning her or her child.
