So here for part a, we can say that the average acceleration for each interval would be calculated by the average acceleration, equaling delta v divided by delta t.
00:13
And we can say that, and this is going to be taken to be the acceleration at the midpoint of any time interval.
00:23
So we can say in the spreadsheet, we can say that a to the end plus one half would be.
00:32
Equal to v to the n plus 1 minus v to the n divided by t to the n plus 1 minus t to the n and so um we can uh the second workbook has the accelerations however this would be the um the excel the formula that you are going to use for part a for part b however we need the position at the end of each interval and this could be equal, this would be x to the n plus one, so the next interval essentially would be equal to the initial position at the nth interval plus one half times v to the n plus v to the n plus one to the next velocity in the data set, and then t to the n plus one, again, minus t to the n.
01:29
And this, we can also represent this as x would be equal to x initial plus the average velocity times delta t.
01:40
However, you want to use this equation because this is much, obviously much more specific.
01:46
And tabulated, it would look like this.
01:50
So these would be the time with the average, with the velocity in kilometers per hour and the velocity in meters per second...
