Well I can`t argue anymore. I`m out of formulas. Shit, I made the horizontal line in the stationary wave but changed it because it seemed too unrealisticdude i did the graph wrong anyway irrespective of the result of our convo i wouldnt benifit in marks
but see my post
Curse my instincts 
I did (1/charge of an electron)=(X/charge found in previous question)
I got a 90 degree phase difference :/
Was the first one similar to that of the force-timeOkay since 24 hours are up,
The graphs were easy. The first one was the same as the force-time one. Just that accelaration was on 3. something. The second one was a right angle triangle. Starting from 0 to 16.8. And then dropping vertically at 2 seconds.
These are absolutely the right graphs
?? I guess in addition to the force-time graph we had to show that the body accelerated from zero to 3. something in 0 s coz the question clearly mentions that the body started from rest which means its initial acceleration should be zero. Isn't the case I may be wrong though ? So basically the graph would be straight vertical line from 0 to 3. something at t = 0 and the remaining one similar to the f-t graph.no way the graph showed constant acceleration how could you show increasing acceleration with constant force?Was the first one similar to that of the force-time
So u mean that the body started from rest at t=0 with 3. something acceleration ? Is it even possible ........ isn't the acceleration supposed to be zero when velocity is zero
?dude tell me cant u have constant acceleration from the start actucally he could have moved 3.5 metres in first second seven in second and so on u can have constant acceleration even at t=0 remeber projectile even at max point g has a value asd need ur help in convincing othersSo u mean that the body started from rest at t=0 with 3. something acceleration ? Is it even possible ........ isn't the acceleration supposed to be zero when velocity is zero
Never-mind I'm currently out of my mind due to Chem. P-5 !!! Furthermore I drew the a-t graph with the particle accelerating from 0 to 3. something in 0 s .... so the line was on the dark vertical axis ..... so if you are right then I can still hope that the examiner won't see it
!!I'm pretty sure after 16.8 it was a horizontal line till the end. As the force became zero, change in momentum was zero.Okay since 24 hours are up,

acceleration can be zero even with constant velocity....newton's 1st law of motion says a body keeps its state of rest or UNIFORM motion unless acted upon by external force,,,,nd force means accelerationSo u mean that the body started from rest at t=0 with 3. something acceleration ? Is it even possible ........ isn't the acceleration supposed to be zero when velocity is zero
They were already
The graphs were generally easy. I can`t discuss the answers here right now. The second graph seemed tricky to many.. But it was easy knowing Change in Momentum equals to Force multiplied by Time. 9 easy marks
