u guys are not allowed to discuss the answers why doesnt everone understand this rule for peace sake -_-44.1
What is the correct scale!? And do we have to mention the scale we took!? :O I just labelled my axes!i thi
ill tell you when the 24 hours finish, you know the rule "sorry"LI did that way....not sure if correct though..btw what did you get for the length of the string??
The second graph didn't drop vertically after 2 seconds. The question didn't mention anything about frictional forces, so I assumed it would carry on with the same velocity, hence it would be a straight horizontal line.Okay 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
Yeah, I drew a straight horizontal line too.for the first graph, i connected the first and last point to give me a downward slope (diagonal-deceleration)...was that wrong? i didnt have time to do the 2nd!
and what was the stationary wave question?? how is it drawn? i drew a straight line through the origin ....
Yeah, I drew a straight horizontal line too.
Didn't know what I was doing
lol, our teacher gave us that paper for our mocks examah okay not just me...coincidence was..yesterday morning before the exam, i asked my teacher about a similar question (M/J 2011 P.23) , where we need to draw a stationary wave on top of the other and T is 0.25....he told me its a straight line but i have no idea why. So when i sow the exam qq, i just decided i would do that rather than leaving it empty...hopefully it's right...coz i know am losing the whole 9 marks on the graph questions!

what was the answer for the change in momentum for graph 2??!!! what do you guys expect the grade threshold to be??!!!
