how was todays paper phy 3!!!!

[ridzi]

OMG it was damn hard :'( man i got almost all q wrong wat about u guyzzzz ????

 

[jackoo123]

Well it wasn't that hard. What was your gradient value ???

 

[jackoo123]

the graph and 2 mcq's were difficult , rest was ok , How much are you predicting

How much was your gradient? ?

 

[ridzi]

very bad result

the graph and 2 mcq's were difficult , rest was ok , How much are you predicting

 

[ridzi]

172 and most of my friends got 172 !!

Well it wasn't that hard. What was your gradient value ???

 

[jackoo123]

I got gradient 146 wbu?

159 so i got 318, and by the way i didn't use my graph since it gave a gradient of 120. i used the given points to find it. do you think it is ok to use those points??

 

[jackoo123]

Do we get marks in the next step for finding V if u used the same graadient ? or the cut marks?

Well yeah I think so

and yeah my gradient was 172 !![/quote]
Hey, Is it ok to use the given points to find the gradient and if so will I lose a lot of marks

 

[-Edge-]

we didnt have to change the length in cm to m or anything?

 

[-Edge-]

we had to change it into meters

Lose marks if didnt change?

 

[-Edge-]

Well if you didn't change then your speed must have been in cm/s which is wrong.
So I guess you might lose marks in the first part but from then on ecf might save you :-D

Ah! great xD
i did divide the value of v with 100 to get answer into meters

if the points are on your line of best fit,

 

[YasminaEmara]

What value did you get for v?

 

[colors]

And what if we didn't change the cm to m in gradient part but changed in v part then? do we get 2 marks for gradient

guys, what did you answer to the first multiple question, the one with 1.00 or 1.000 i am really confused.. :/ Also, in question 7, free fall one, what did you say about repeats? i couldn't think of anything there..

hey please dont discuss answers until 24 hrs have passed!

What if you get a value of v below 330. I got 326 ms^-1...
Reply Quick ... :/

how do you guys find the gradient
+ the first question about uncertainties does anyone know how to solve them?

how did you find v?

 

[Amsal1998]

how did you find v?

Like First i graphed it. Then I found the gradient and i got 16300 cms^-1 them i changed it to meters so 163 ms^-1. Then I multiplied it by 2 using the equation they gave by comparing it to the graph (The gradient was half the speed) and i got 326 ms^-1.
