Alright for question 47.
00:06
We have a lot of work here so aces that we have to look at time and time is going to equal distance d over velocity and what we're looking at for time so called t.
00:31
Yes 3000 the link in our initial velocity our starting point and when we round to one decimal that gets us 15.3 seconds.
00:56
So that's a now be asked us what happens when we start at nine cm and not zero cm.
01:10
Okay so we'll look at t equals 3000 still but for our velocity is now going to be 180 because we're looking at the velocity at nine centimeters and we can actually use the calculator here.
01:30
Two defied and rounding to one decimal we have approximately 16.7 seconds now for c we'll use regression.
01:50
So let's enter this into your list.
01:52
I'm going to press stat edit and i'm going to enter my values zero for x it's going to be zero through nine the integers or five six 78 fine.
02:23
Then i'll go to list too.
02:25
And to enter those values starting in syria i have 195.6.
02:37
195 points to you.
02:42
1:94.2 velocity is decreasing.
02:48
193.
02:51
191.5 189.8...
