00:00:00.040 --> 00:00:03.649 A:middle L:90%
for this problem. I think I'm going to borrow
2
00:00:05.839 --> 00:00:11.109 A:middle L:90%
a concept from the From the next section. That
3
00:00:11.109 --> 00:00:16.929 A:middle L:90%
is Gravity is ah, is her conservative force field
4
00:00:17.030 --> 00:00:19.780 A:middle L:90%
. That means he's a Grady in off some potential
5
00:00:19.789 --> 00:00:24.660 A:middle L:90%
scaler function. If that is the case, the
6
00:00:24.670 --> 00:00:28.190 A:middle L:90%
energy and the work down is simply the difference off
7
00:00:28.190 --> 00:00:30.739 A:middle L:90%
the potential. Yes, I know you can go
8
00:00:30.739 --> 00:00:34.850 A:middle L:90%
through all the process and to set up the line
9
00:00:34.859 --> 00:00:37.950 A:middle L:90%
a pro and try to figure out Hold this up
10
00:00:39.939 --> 00:00:43.289 A:middle L:90%
. What is, uh, actually work down on
11
00:00:43.299 --> 00:00:47.670 A:middle L:90%
the computer half that TR likes how it did many
12
00:00:47.670 --> 00:00:51.009 A:middle L:90%
times in our problems, but I think for these
13
00:00:51.009 --> 00:01:00.579 A:middle L:90%
problems are necessary. The work tango simply p a
14
00:01:00.590 --> 00:01:06.980 A:middle L:90%
difference in in potential and what is near the front
15
00:01:08.890 --> 00:01:15.659 A:middle L:90%
. Uh, the potential energy will be just be
16
00:01:15.659 --> 00:01:21.909 A:middle L:90%
the mass times gravity constant, which is in this
17
00:01:21.909 --> 00:01:26.150 A:middle L:90%
unit system, is thiss on times the height,
18
00:01:26.739 --> 00:01:37.819 A:middle L:90%
which is she's thiss as your masses. This twenty
19
00:01:37.819 --> 00:01:42.549 A:middle L:90%
five, there was a walk down by a man
20
00:01:42.560 --> 00:01:48.790 A:middle L:90%
. So it's actually sir the stuff he's carrying twenty
21
00:01:48.790 --> 00:01:53.450 A:middle L:90%
five pounds, and you can you can simplify the
22
00:01:53.450 --> 00:01:56.650 A:middle L:90%
unit and the number of further
