Mechanical only, and was there a relation between the f and x? There was no relation right, as k is quite different for both

I got a negative gradient of -0.03 and a y-intercept of +10.2 something. I have one question - there must be variations in values for all candidates' answers, so on what basis do the examiners mark our answers? Do they grade us on basis of our method or whether our answers lie within the range they determine?

What about the relation in Q2? I got a big difference between the two constants k, so they are not related, right?

What about the constants k, what did you guys get? Did the time increase or decrease as you changed?

Time decreased as x decreased. My results supported the equation as I got only 11% difference between my two values of k.
