Studi tentang peran keluarga membentuk sikap sosial siswa SD bidang studi ips menyusun rencana proposal​

Forgive me. When I hear a person say "I'm not quite sure", what I hear is "I have no clue".
This is not an awfully tough problem, but there IS one big piece of information missing: When the 'burners' ignite, do they push in the same direction it's already moving, and speed it up ? Or do they push opposite to its motion, and slow it down ? the question doesn't say.
For reasons that I won't go into, I think we should assume that the 'burners' are on the back of the rocket, pushing in the same direction it's already going, and speeding it up.
So we have a 1,000 kg object. Suddenly a force of 200N kicks it from behind, and starts speeding it up.
Do you remember . . . (Force) = (mass) x (acceleration) ? We know the force and the mass . . . (200N) = (1,000 kg) x (acceleration) Acceleration = 200/1,000 = (0.2 meter per second) per second. That's how its speed grows during the burn. In 300 seconds, it will gain (300) times (0.2 meter per second) = 60 m/sec.
It was originally moving at 40 m/s and the 'burners' added 60 m/s during the 5-minute burn. So when the burners shut off, it's moving 100 m/s .
If the burners were pushing the other way, slowing it down, then in 300 sec it would lose 60 m/s of speed. Its final speed would be (40) + (-60) = -20 m/s. That means 20 m/s in the opposite direction.
That's the answer you need, and the math you use to find it.
But there's still something wrong with this problem ... in the real world of space travel, it's a bogus question. The ship doesn't remain 1,000 kg while the thrusters fire for 5 minutes. The thrusters use fuel to burn, and the mass of the ship keeps decreasing and decreasing while fuel burns.
So when the real aerospace engineers do this same problem, they still use (force) = (mass) x (acceleration), but they're working with a mass that's constantly changing. You can see that this makes the problem a little more complicated, and to work it, they use "Calculus". You can get into Calculus before you graduate High School, if you want to. The things you can do with it can really give you a feeling of power.

After applying a force of 200 N for 300 seconds, the final speed of the 1000 kg rocket increases from 40 m/s to 100 m/s, resulting in a total speed of 100 m/s. This is calculated using Newton's second law to find acceleration, followed by computing the change in velocity over time. The calculation steps include determining acceleration, change in velocity, and final speed based on the initial velocity.

Jawaban:A. JudulStudi tentang Peran Keluarga dalam Membentuk Sikap Sosial Siswa Sekolah DasarB. Latar BelakangKeluarga merupakan lingkungan pendidikan pertama dan utama bagi anak. Melalui keluarga, anak belajar nilai, norma, dan perilaku sosial. Peran keluarga sangat penting dalam membentuk sikap sosial siswa SD, misalnya sikap disiplin, gotong royong, menghormati orang lain, dan tanggung jawab. Oleh karena itu, perlu dilakukan penelitian mengenai sejauh mana peran keluarga berpengaruh terhadap sikap sosial siswa SD.C. Rumusan Masalah1. Bagaimana peran keluarga dalam membentuk sikap sosial siswa SD?2. Bentuk sikap sosial apa saja yang dikembangkan melalui keluarga?3. Faktor apa yang mendukung dan menghambat peran keluarga dalam pembentukan sikap sosial siswa?D. Tujuan Penelitian1. Mengetahui peran keluarga dalam membentuk sikap sosial siswa SD.2. Mendeskripsikan sikap sosial siswa yang dipengaruhi keluarga.3. Mengidentifikasi faktor pendukung dan penghambat peran keluarga.E. Manfaat PenelitianTeoritis: Menambah wawasan dalam bidang ilmu IPS terkait pendidikan keluarga.Praktis:Bagi siswa: membentuk sikap sosial positif.Bagi guru: memahami peran keluarga dalam pendidikan sosial.Bagi orang tua: menjadi pedoman dalam mendidik anak di rumah.F. Kajian Pustaka (singkat)Konsep keluarga dalam pendidikan.Konsep sikap sosial menurut IPS.Hubungan peran keluarga dengan perkembangan sosial anak.G. Metodologi PenelitianJenis penelitian: Deskriptif kualitatif.Subjek penelitian: Siswa kelas IV–VI SD dan orang tua mereka.Teknik pengumpulan data: Observasi, wawancara, dan angket.Teknik analisis data: Reduksi data, penyajian data, dan penarikan kesimpulan.H.
