Gmail lagi

another easy quandary. during my short vacation in kl, i stumbled across my old spm exam papers whilst a spring-cleaning sesh (that's some holiday) at home.



the answer to this question gets you a Gmail account (i think millions of people would have 'em by now, but what the heck):

which science subject taught in the pure science stream would these questions you see above come from?

the first two people person with the correct answer gets a Gmail account each. as usual, answers, along with email address, in the comment box below.

oh ya. if you already have a Gmail address please don't bother. :)

UPDATE: since the answer is now known to all, and the person who answered the question correctly already have a Gmail address, i have a new question:

ANSWER QUESTION 2(b) IN THE SPM FIZIK PAPER ABOVE. SHOW HOW YOU COME TO THE ANSWER.

oh ya, do it in BM as well. hahaha.

Hmmm... is it 43.5 m/s?

(m1 + m2)v = m1v1 + m2v2
(300)(0) = 290(-1.5) + 10(v2)
0 = -435 + 10v2
v2 = 43.5

Betul? Or have I completely lost whatever Physics knowledge I ever possessed?

P.S. I have Gmail of course, but I couldn't pass a chance to practice my rusty Physics skills...
