man this was T1!!V/T2 = acceleration = 0.3
T2=V/0.3
We are currently struggling to cover the operational costs of Xtremepapers, as a result we might have to shut this website down. Please donate if we have helped you and help make a difference in other students' lives!

thank youV/T2 = acceleration = 0.3
T2=V/0.3
MiniSacBallI guess the problem is in the third part. An easy way to do this question is to consider the movement of the signal from its highest point, where its u = 0. Now we know that total time is underroot 17s. Thus when conisdering only the returing time, it would become underroot 17/2s
Now use S = 1/2 (10) (underroot 17/2)square
S = 5 (17/4)'
S = 21.25m
Thus its height above the cliff was 21.25 Now just use the third equation of motion with v = 0 and you will get the answer

Q3 iii i need help please! Explain.
V/T2 = acceleration = 0.3
T2=V/0.3
http://papers.xtremepapers.com/CIE/...S Level/Mathematics (9709)/9709_w13_qp_43.pdfnope , that's it for now!
the time above the cliff =2* speed when reached at cliff/accelerationhttp://papers.xtremepapers.com/CIE/Cambridge International A and AS Level/Mathematics (9709)/9709_s13_qp_41.pdf
Q3 iii i need help please! Explain.
so much physics like i hope i took mechanicsthe time above the cliff =2* speed when reached at cliff/acceleration
speed at the cliff= 10*√17 / 2 = 5√17
speed at bottom = u =? distance = 40 m, acceleration = g = 10 m/s²
v²=u²+2as
u²=2*10*40-(5√17)²)
u=√1225
=35 m/s

Still it's tough!so much physics like i hope i took mechanics
statistics on the other hand is totally different
its is like all the hard topics of physics made dense in the paperStill it's tough!

Q5 plz man
tom is my exam
thank you mananswered on above post.
there are only three people active on this thread and all are doing M1 paper 4. discuss.who's done with mechanics? want to discuss paper 4
For almost 10 years, the site XtremePapers has been trying very hard to serve its users.
However, we are now struggling to cover its operational costs due to unforeseen circumstances. If we helped you in any way, kindly contribute and be the part of this effort. No act of kindness, no matter how small, is ever wasted.
