SOALAN RAMALAN/ BOCOR/ SPOT/ TILIKAN/ TEROPONG DLL PHYSICS SPM 2010

Hari selasa tadi kelam kabut sket. yela, masing tertanya-tanya, jumaat ni cuti ke idak?... memang mejadi satu misteri hinggalah mohor besar guru-guru sebulat suara menyatakan jumaat cuti..horeyyyyy.

 bukan ape, sebab takda ribut taufan tentang sekolah cuti pada hari jumaat, masing-masing dok releks lagi...bile diumumkan, kelam kabut menyiapkan benda-benda yang nak di submit, dengan slip exam form4 dsb. peperiksaan yang amat panjang, dekat 3 minggu, implikasinya terbawa sampai ke hujung hari persekolahan. masa yang pendek untuk rait ketas dsb...

tapi semua setel, alhamdulillah...analisis cikgu siti buat kot..heheh

dan biasa lah hari akhir, pelajar form5 yang nak amek spm bersalaman bermaafan... tiada sesiapa yang membawa bawang untuk dikupas.

"cikgu, takde soalan spot ke???"..alah...cikgu tak sempat nak spot2 la...(aku rasa budak2 ni lagi pandai menyepot...FB bagai wadah perkongsian maklumat...tak dinafikan..)

cite panjang2 baru nak bagi tips. ekceli, ni penulis amek dari websites lain. kopi dan tampal aje...jadi sesame la kita berusaha.

Question 1
A ball is falling from the top of the building. If the height of the building is 250 m. What is the final velocity before it reaches the ground?

answer :


h = -250 m
u = 0 m/s

v² = u² – 2gh

v² = 0 – 2 (10)(-250)

v  = 70.711 m/s

m/s = mengapa nilai h perlu negatif? ini kerana h = h final - h initial

Question 2
Given the pulley system below

Find the acceleration?

 answer :


Fx = T1 = Ma   .....................i


Fy = T2 = mg - ma ........ii  (sebab turun ke bawah)
(gunakan konsep lift, naik , bertambah berat (mg + ma) , turun jadi bertambah ringan, (mg - ma)

so,  


  T1 = T2
 Ma = mg - ma      ....... (selesaikan untuk dapat  a, kaedah matematik biasa)

    a = mg / (M + m) 

    a = 5(10) /(10 + 5) = 3.33 ms^-2

Question 3
Define the meaning of conservation of momentum?

answer : selak buku la ye..

Question 4
A car of 500 kg, traveling at 30 m/s rear ends another car of 600 kg, traveling at 20 m/s. in the same direction The collision is great enough that the two cars stick together after they collide. How fast will both cars be going after the collision?

answer : 


bila melekat, pelanggaran tak kenyal, jadi jisimnya bergabung dan velocity nya pun sama untuk car1 and car2.

m₁u₁ + m₂u₂ = (m₁ + m₂)v

m_{1 = 500 kg}

u_{1 = 30 m/s}

m₂ = 600 kg

u_{2 = 20 m/s}

_{subtitute into the formula}

_{500 kg (30 m/s) + 600kg (20 m/s) = (500 + 600 ) v}

_{v = 24.545 m/s}
