how was M1 42
how come???? V^2 = U^2 +2as is only applied to CONSTANT acceleration question and this isn't a constant acceleration question :S:S -
how was M1 42
how did u get that speed then if t = 0 so the velocity should be equal to zero according to the equation given ? -
how was M1 42
u r making me sad bro :( cuz that kinetic energy question is easy but i did a simple mistake that would take marks off me..i had one velocty 4.44 and the other one 13.1 instead of 15 for using the acceleration 0.4 instead of 0.2 arghhh :( -
how was M1 42
how did u get the last part of the last question ? explain pls -

i had troubles with accuracy in this exam..math and in the morning on a FRIDAY like come on..for sure my brain wont be concentrating -_- -
Mechanics M1: Post your doubt here
man i did a silly mistake that ruined my whole question..i calculated the acceleration on the top 0.4 instead of 0.2 and continued my working like that how many marks u think i will get off ? -

umm bro how did u get F to be 2000 ? -
statistic (s1) or mechanics(m1) in As-level?
u should definitely go with statistics if u will study commerce cuz mechanics is for engineers. if u love physics the forces parts then u would love mechanics but as a commerce student its much better to take statistics -

y is it a parabola and not a straight line? isn't the velocity increasing with a constant rate ? -

can someone explain to me why the constant value in q7 part 2 for the first integration is 5? y the time is zero and not 0.5!! :S:S: http://www.xtremepapers.com/papers/CIE/Cambridge%20International%20A%20and%20AS%20Level/Mathematics%20(9709)/9709_w08_qp_4.pdf -

np mate..i am glad it helped u :) -

W.D - WDr = KE + PE thats the formula..thats it! KE gets a negative value if its kinetic energy loss and it gets a positive value if its kinetic energy gain and some goes to the PE..
