Sebiji bola berjisim 6 kg bergerak ke arah utara dengan kelajuan tetap 12 m/s,manakala sebiji lagi bola berjisim 5 kg bergerak ke arah selatan dengan kelajuan tetap 10 m/s.Beberapa saat kemudian,kedua-duanya pun berlanggar secara tepat.Selepas berlanggaran,kedua-duanya bercantum.Cari:

1)Jumlah momentum sistem.
2)Laju kedua-dua bola selepas berlanggar.
3)Arah gerakan kedua-dua bola selepas berlanggar.


1. M1V1 + M2V2 = (6x12) + (5x10) = 72kgm/s + 50kgm/s = 122kgm/s
2. (122/11)m/s = 11.09 m/s
3. Utara

1.Formula betul,tapi jawapan dan penggantian salah.
2.Kalau yang no. 1 betul,maka yang ini anda sepatutnya akan betul.
3.betul

Sikit lagi...cuba lagi...

Kalau yg ni...

bola 5kg bergrak -10m/s sbb bergerak pada arah bertentangan

1. M1V1 + M2V2 = (6x12) + (5x-10) = 72kgm/s - 50kgm/s = 22kgm/s
2. (22/11)m/s = 2 m/s
3. Utara

hehehe.. aku tak paham apa maksud "Jumlah momentum sistem"... Ingat kena kira jumlah tenaga guna equation yg ada 1/2*apa benda tah tu....
takpe.. boleh refresh benda2 lama ni semula...

Takpe...aku tak kisah..
Walaupun aku jawab guna rules IUPAC dalam buku Organic Chemistry.

Aku cadangkan cuba buat soalan sendirilah.Kalau ambil soalan dari link yang lain,memang orang boleh dapat jawapan.Sebab tu aku suka buat soalah Physics atau maths.Cuma perlu kuasai konsep je,kita boleh buat soalan sendiri..
