00:00:00.040 --> 00:00:05.129 A:middle L:90%
so finding the center of mess. This problem Let
2
00:00:05.129 --> 00:00:09.470 A:middle L:90%
me explain a setup First. First from the textbook
3
00:00:09.650 --> 00:00:12.060 A:middle L:90%
, you can find a former off Mass and center
4
00:00:12.060 --> 00:00:15.320 A:middle L:90%
of mass. In case you don't remember, this's
5
00:00:15.330 --> 00:00:20.859 A:middle L:90%
the former and does Andi We need a Paramount try
6
00:00:20.859 --> 00:00:22.960 A:middle L:90%
harder to do this in the growth we need a
7
00:00:22.960 --> 00:00:26.870 A:middle L:90%
parametric sex It was to call society. Why was
8
00:00:26.879 --> 00:00:35.000 A:middle L:90%
to society and his ex ex is post now Negative
9
00:00:35.009 --> 00:00:37.450 A:middle L:90%
. So it's a dry health off a certain look
10
00:00:37.840 --> 00:00:40.390 A:middle L:90%
so that biggest egos from negative pie over to to
11
00:00:40.390 --> 00:00:43.759 A:middle L:90%
power too. And we'Ll have to figure out GS
12
00:00:43.759 --> 00:00:49.460 A:middle L:90%
which was dx DT Square prostitute y squared Wei have
13
00:00:49.460 --> 00:00:54.250 A:middle L:90%
square with force so is two and DT So once
14
00:00:54.250 --> 00:00:58.469 A:middle L:90%
we have everything is pretty much just computation Some competition
15
00:00:58.469 --> 00:01:00.850 A:middle L:90%
left. So, for example, we compute the
16
00:01:00.850 --> 00:01:06.709 A:middle L:90%
master first. That should be t goes from Nephew
17
00:01:06.709 --> 00:01:11.040 A:middle L:90%
Pie over to pie over too in this problem that
18
00:01:11.049 --> 00:01:14.569 A:middle L:90%
that's it, he's simply okay, So we have
19
00:01:15.439 --> 00:01:23.000 A:middle L:90%
Hey, the s is to tt So we got
20
00:01:23.010 --> 00:01:27.879 A:middle L:90%
to k times the difference between bunk, which is
21
00:01:29.060 --> 00:01:36.450 A:middle L:90%
pie or to pike and this hump you, huh
22
00:01:37.340 --> 00:01:41.620 A:middle L:90%
? The center ofthe mess. So the x coordinate
23
00:01:41.620 --> 00:01:46.799 A:middle L:90%
is keeping by this. Head X is to co
24
00:01:46.799 --> 00:01:53.340 A:middle L:90%
sign T and Ro is K and the esus to
25
00:01:53.340 --> 00:02:01.920 A:middle L:90%
TT. So have we, um, pulled for
26
00:02:01.920 --> 00:02:23.150 A:middle L:90%
Kay coastline t That should keep us our society.
27
00:02:23.509 --> 00:02:27.150 A:middle L:90%
We are one minus nifty once. So is too
28
00:02:30.219 --> 00:02:37.750 A:middle L:90%
on similarities This artist's X coordinate And why coordinate is
29
00:02:37.759 --> 00:02:42.699 A:middle L:90%
this? You're droll? Ah, why should be
30
00:02:42.710 --> 00:02:50.949 A:middle L:90%
to sign He and roll is okay. Yes is
31
00:02:51.770 --> 00:03:02.150 A:middle L:90%
he? And similarly we have thiss I have signed
32
00:03:02.189 --> 00:03:08.870 A:middle L:90%
it. So your nephew of course I NT we
33
00:03:08.870 --> 00:03:13.629 A:middle L:90%
still have four k over and never co signed the
34
00:03:13.629 --> 00:03:19.330 A:middle L:90%
forms here to here. But they they're both zero
35
00:03:23.840 --> 00:03:29.509 A:middle L:90%
. What? They're both here. So their difference
36
00:03:29.509 --> 00:03:47.939 A:middle L:90%
should be sure he's here. So? So the
37
00:03:47.949 --> 00:03:59.840 A:middle L:90%
mess should be Should be two pi k in the
38
00:03:59.849 --> 00:04:05.289 A:middle L:90%
center ofthe masses we compute. It should be hate
39
00:04:05.300 --> 00:04:09.770 A:middle L:90%
kay over him And the wild card they should be
40
00:04:09.780 --> 00:04:12.949 A:middle L:90%
zero has to make sense is symmetric with respect.
41
00:04:13.960 --> 00:04:17.430 A:middle L:90%
Except this is a right hell Part of the circle
42
00:04:25.370 --> 00:04:28.069 A:middle L:90%
. Sorry, I haven't feel so em is to
43
00:04:28.069 --> 00:04:31.810 A:middle L:90%
Pike. So we should replace this by to Pike
44
00:04:33.019 --> 00:04:39.540 A:middle L:90%
and Dash B four over Pi We should use this
45
00:04:39.540 --> A:middle L:90%
number
