00:00:01.899 --> 00:00:04.269 A:middle L:90%
welcome to a new problem. This time we have
2
00:00:04.269 --> 00:00:07.049 A:middle L:90%
an astronaut in space and they happened to have a
3
00:00:07.049 --> 00:00:10.269 A:middle L:90%
mass mass of astronaut. So this is what's given
4
00:00:10.910 --> 00:00:14.810 A:middle L:90%
well, given that the mosque often astronaut, is
5
00:00:15.419 --> 00:00:20.280 A:middle L:90%
sixty eight point five kilograms and then we're also given
6
00:00:20.280 --> 00:00:25.660 A:middle L:90%
that this is, you know, they're orbiting space
7
00:00:25.670 --> 00:00:29.820 A:middle L:90%
. That's the astronaut, okay? And the mass
8
00:00:29.820 --> 00:00:34.409 A:middle L:90%
happens to be sixty point five kilograms. And the
9
00:00:34.409 --> 00:00:40.259 A:middle L:90%
aston what happens to throw Wei? Uh um a
10
00:00:40.270 --> 00:00:41.969 A:middle L:90%
tool. You know, we don't know what the
11
00:00:41.969 --> 00:00:46.740 A:middle L:90%
tool is, but the astronaut caused it The tool
12
00:00:46.750 --> 00:00:50.159 A:middle L:90%
this way. Meaning that they're gonna have a push
13
00:00:50.159 --> 00:00:53.939 A:middle L:90%
start because of Newton's stud law. So Newton start
14
00:00:53.939 --> 00:00:57.469 A:middle L:90%
law, say's the action reaction forces the equal and
15
00:00:57.469 --> 00:01:03.340 A:middle L:90%
opposite the mass off too, happens to be two
16
00:01:03.349 --> 00:01:07.950 A:middle L:90%
point two five kilogram. And the tool is moving
17
00:01:08.079 --> 00:01:11.519 A:middle L:90%
with the velocity that lost you. The two is
18
00:01:11.900 --> 00:01:17.219 A:middle L:90%
three point two zero meters per second. We don't
19
00:01:17.219 --> 00:01:19.980 A:middle L:90%
know what the velocity of the astronaut is, but
20
00:01:19.989 --> 00:01:22.260 A:middle L:90%
that's not It is moving in the opposite direction.
21
00:01:22.939 --> 00:01:26.500 A:middle L:90%
So that's what we're given. I want to find
22
00:01:27.310 --> 00:01:30.810 A:middle L:90%
the, you know, find the velocity of the
23
00:01:30.810 --> 00:01:36.129 A:middle L:90%
astronaut. Okay, So you're gonna use the law
24
00:01:37.040 --> 00:01:45.950 A:middle L:90%
off conservation Oh, off momentum. Which says that
25
00:01:46.799 --> 00:01:51.569 A:middle L:90%
the initial momentum off the system equals to the final
26
00:01:51.569 --> 00:01:53.689 A:middle L:90%
momentum off the system. The initial momentum of the
27
00:01:53.689 --> 00:02:00.420 A:middle L:90%
system. This happens to be the, um the
28
00:02:00.430 --> 00:02:02.709 A:middle L:90%
tools. So we have the two. They're moving
29
00:02:02.709 --> 00:02:06.608 A:middle L:90%
in opposite direction. So the tool, the mass
30
00:02:06.617 --> 00:02:09.948 A:middle L:90%
ofthe two times the velocity off the two equals to
31
00:02:09.948 --> 00:02:13.837 A:middle L:90%
the mask off the astronaut times the velocity off the
32
00:02:13.837 --> 00:02:15.497 A:middle L:90%
asteroid on DH. So we want to solve it
33
00:02:15.508 --> 00:02:17.707 A:middle L:90%
. Lost it. They asked or not that going
34
00:02:17.707 --> 00:02:23.427 A:middle L:90%
to give us the aid? Because too MTV t
35
00:02:23.478 --> 00:02:25.907 A:middle L:90%
over m A. We plug in the numbers the
36
00:02:25.907 --> 00:02:30.187 A:middle L:90%
mass of the astronautical because sixty eight point five kilograms
37
00:02:30.707 --> 00:02:38.568 A:middle L:90%
Um so sorry, dude. The to the tool
38
00:02:38.578 --> 00:02:43.348 A:middle L:90%
the tool is two point two five kilograms of muscle
39
00:02:43.348 --> 00:02:45.798 A:middle L:90%
. The tools to point two five program in the
40
00:02:45.798 --> 00:02:51.068 A:middle L:90%
velocity of the two is three point two kilometres per
41
00:02:51.068 --> 00:02:53.867 A:middle L:90%
second. Then divide that by the mass of the
42
00:02:53.867 --> 00:02:55.717 A:middle L:90%
astronaut, which happens to be given a sixty eight
43
00:02:57.258 --> 00:03:05.298 A:middle L:90%
point five kilograms that will give us a final velocity
44
00:03:05.298 --> 00:03:08.348 A:middle L:90%
off the astronaut. That happens to be five.
45
00:03:08.348 --> 00:03:12.228 A:middle L:90%
Plug in these numbers, they get two point two
46
00:03:12.228 --> 00:03:15.627 A:middle L:90%
five times, three point two. Then you divide
47
00:03:15.638 --> 00:03:22.328 A:middle L:90%
that by sixty eight point five kilograms in a super
48
00:03:22.328 --> 00:03:24.937 A:middle L:90%
small number. And that makes sense because, you
49
00:03:24.937 --> 00:03:29.038 A:middle L:90%
know, the Imagine a tool is trying to push
50
00:03:29.038 --> 00:03:30.627 A:middle L:90%
the astronaut backwards. But, you know, it's
51
00:03:30.627 --> 00:03:36.418 A:middle L:90%
in outer space, so still. Okay, Still
52
00:03:36.418 --> 00:03:42.237 A:middle L:90%
some impact. Does your point one zero five two
53
00:03:43.367 --> 00:03:45.108 A:middle L:90%
. Okay, five, one. Sorry. One
54
00:03:45.117 --> 00:03:47.018 A:middle L:90%
, two, five, one. We gotta change
55
00:03:47.027 --> 00:03:53.967 A:middle L:90%
this to one change. This one right here of
56
00:03:53.978 --> 00:04:11.557 A:middle L:90%
this is one that Oh, you mean that this
57
00:04:11.557 --> 00:04:15.608 A:middle L:90%
is one meters per second. Hope you enjoy the
58
00:04:15.617 --> 00:04:17.708 A:middle L:90%
video. Uh, make sure you have a wonderful
59
00:04:17.708 --> 00:04:20.208 A:middle L:90%
day. We wanted to find the velocity of the
60
00:04:20.208 --> 00:04:25.007 A:middle L:90%
astronaut when they throw a tulip in outer space.
61
00:04:25.017 --> 00:04:25.858 A:middle L:90%
Okay, Thanks. Bye.
