Step-by-step explanation:
Key to this method is remembering that
So, if you divide the coefficient of x by 2 and square it, that will complete the square. With that in mind, things are easy.
6/2 = 3, so add
So, c=9
Similarly, for the other two,
You don't really have to worry about the sign, since squaring will always make it positive
The average acceleration of an object is calculated as the final speed minus the initial speed divided by the elapsed time.
So:
Where
= final speed
= initial speed
= elapsed time.
Thus:
The acceleration of the cyclist is:
a = 2.667
The acceleration of the car is:
a = 3.75
The average acceleration of the car is higher than the average acceleration of the cyclist.
