re: HSC Physics Marathon Archive

A particle accelerator is capable of accelerating a proton to a speed of 0.99c. Calculate the mass of this proton as measured from the reference frame of the collider.

Use mass dilation equation

I've almost done all of the hsc questions for space and I haven't seen one which requires you to find thrust. I wouldn't worry

re: HSC Physics Marathon Archive

so which one's correct? i get different answers with both
No, this is the derivation process.
I simply explained that the sum of forces acting on a rocket during launch is thrust minus mass due to gravity
So the final equation for thrust is T = mg+ma

How do i use mass dilation equation?
mv = mo/sqrt(1-v^2/c^2)
When travelling at relativistic speeds, outside observers will see that the mass of the proton increases
So sub mo = mass of proton (from data sheet) and you should get a mass larger than the stated mass

Ah...thx.

Just had a memory lapse which mass was m zero.

and forgot mass of proton was on data sheet.
