No, the equation for c was (gmh)/(m x change in temperature),so the masses cancelled out, so C was independent of mass in this case. -

Did anyone get 1.73 x 10^33 for the mass of S2?

You should have added the vertical component of the water hosehopefully you should get some marks for the use of the component however, maybe drop 1 or 2 marks.

For the reaction for the hose pipe dude, I did:
Resolve upwards, R + vertical component of the speed = his weight, correct?Last edited by Reda2; 20-06-2016 at 11:07. -

Thats what i thought, but surely, when the mass is doubled, the energy is doubled (mgh) so wouldnt the temperature increase aswell? I understand the equation obviously shows that temperature changeshouldnt increase, but i cannot understand how this is the case in a physical way. -

for the fireman question, i calculated the weight of the fireman and took away the vertical component of the water hose so i got around 830N i think -

I thought it was 7pi/6 out of phase, because from A to F it was 3pi/2 and from A to B I thought it was pi/3..... so B to F being 7pi/6
