00:00:00.340 --> 00:00:02.189 A:middle L:90%
he has clear. So when you right here.
2
00:00:02.279 --> 00:00:06.919 A:middle L:90%
So we have. Except T is equal to eight
3
00:00:06.919 --> 00:00:15.619 A:middle L:90%
sign. So this is given. Next We're gonna
4
00:00:15.619 --> 00:00:23.649 A:middle L:90%
find the derivative. So we get eight co sign
5
00:00:29.839 --> 00:00:32.850 A:middle L:90%
her derivative is equal to the velocity And to find
6
00:00:32.850 --> 00:00:36.200 A:middle L:90%
acceleration, we just have to derive it one more
7
00:00:36.200 --> 00:00:49.880 A:middle L:90%
time. We get negative eight sign. It's a
8
00:00:49.880 --> 00:00:57.250 A:middle L:90%
party for part B. We have the velocity function
9
00:00:58.380 --> 00:01:00.109 A:middle L:90%
. This is equal to V. This is equal
10
00:01:00.109 --> 00:01:06.290 A:middle L:90%
. Today we have except t, which is the
11
00:01:06.290 --> 00:01:10.170 A:middle L:90%
position function. So worried you were gonna plug in
12
00:01:10.180 --> 00:01:18.129 A:middle L:90%
to pie over three pretty for all three equations when
13
00:01:18.129 --> 00:01:23.310 A:middle L:90%
we get four square root of three, which is
14
00:01:23.319 --> 00:01:33.200 A:middle L:90%
around six point 93 centimeters. Next we're gonna plug
15
00:01:33.200 --> 00:01:44.200 A:middle L:90%
it into our velocity function. So we get negative
16
00:01:44.209 --> 00:02:00.859 A:middle L:90%
four centimeters per second and finally our acceleration function which
17
00:02:00.859 --> 00:02:09.650 A:middle L:90%
give this negative six points 93 centimeters per second square
18
00:02:10.340 --> 00:02:14.159 A:middle L:90%
. Since the velocities negative, it's going to the
19
00:02:14.159 --> A:middle L:90%
left
