Dats exactly what i drew But..........................9 marks rite?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 thats right, the graphs you have made. And even if some of the students managed to get the y axis right, they'll score marks too. The stationary wave graph is quite tricky, nobody knows the correct answer so let it be for the mark scheme

how ws the stationary wave made ?
i made horizontal line because i saw a past paper with the same or like question
Ofcourse. I confirmed with my teachers. If nothing, we`ve scored 8 marks here alteast.
I hope thats the right answer then, nd i'd been worried sick over it yesterday,,,,although todays paper ws easy peezy so no worries
When your force is zero, momentum is zero. Thats the question.There was nothing about velocity.
can u describe how the graphs were supposed to be
Like I said,
So you're saying the object came to an instantaneous halt after the force acting on it was removed?
no it remained flat after two seconds -_-
no not necessary, the resultant force becomes zero so object CAN continue with constant velocity
dude the gradient of the momentum time graph was the force so if u changed it to zero you were supposing that for a sec the force is infinity
really ws it of change in momentum ? i thought it ws just plain momentumJeez guys, ever heard of the formula :
Change in momentum equals force multiplied by time. The graph was for change in momentum. If zero multiplies by time and gives you a value, then you can prove your point
dude i did the graph wrong anyway irrespective of the result of our convo i wouldnt benifit in marksJeez guys, ever heard of the formula :
