Thanks a ton but is it possible for you to show me the graph. If you can...Anyways, Thanks.According to what the marking scheme says, the graph is more like an upward slope, then an inverted mountain:
If t = 0, the initial velocity = 5, so the graph must start at t = 0 and v = 5.
After that, from t till T1, the question states that the velocity is increasing. This can be shown on the graph as a curve going upwards to a positive maximum velocity.
From T1 till T2, the velocity decreases, so the graph should then show a decreasing velocity (however, the velocity must NOT be negative because the velocity only decreases, it doesn't change in direction) till the positive minimum, which they've asked you to calculate - it's the velocity at T2, 5 ms-1.
Lastly, since it says that the velocity increases after T2, the graph should show an increasing velocity curve.
This is what i've been able to gather from the mark scheme, which is not so strict on the values at which it goes to a maximum and minimum, etc.
Hope this Helped!
Good Luck for all your exams!
first dealing with the right hand forces:
i dont know why that made me laugh lmaoYay! I did that paper.
Hey.....still in need?http://papers.xtremepapers.com/CIE/Cambridge International A and AS Level/Mathematics (9709)/9709_s11_qp_42.pdf
help me with Question 6 (i)
and question :5 (ii)
Comon people its urgent anyone
For question 6 i) Use cosine rule to find the angles A and B.Once u know them....resolve the forces as usual...PS: the angles u found (A and B) are also the angles that the strings make with the horizontal x axis. So, now resolving makes sense eh? both the strings have the same tension as they have the same length nd they make the same angle with the horizontal. So finally it will be 2Tsin36.9 = 6.....T=5Nhttp://papers.xtremepapers.com/CIE/Cambridge International A and AS Level/Mathematics (9709)/9709_s11_qp_42.pdf
