I didn't knw what they were asking.. But resultant force should be 0 cuz they told u that the block was in equailibrium . Therefore no resultant force.

that sounds right actually, didnt think of that

Not 100% sure but it was a 2 mark question so there should be some maths in it. But besides that I think the question was worded "what is the resultant force from the floor". Its only the resultant force on the body that was zero, the floor still had to supply the Friction and the Reaction to keep the block in equilibrium?

Ugh i did the same thing, i used 800000 * (1/80) for the weight down the slope. This meant i got the acceleration in the wrong direction too =-(. Thankfully the rest of the paper was okay.

Well, that was awful. Damn mechanics

This. M1 was quite possibly the most boring exam I've had to prepare for this year.

true, i dont remember exactly how it was worded, but i just presumed it meant all the forces from the floor on the block, sometimes when its worded weird they give you a mark if you fall into the trap and do it wrong haha

What did people get for the boat race where you had to plot the graph??

Really downed by this exam. I did reasonably in the past papers but this just took me out completely. I was hoping for a 15 mark section on projectiles or something but we only got 7 marks for it. The last questions with the boat races were awful and so were the questions with the 17 trucks or something. Nasty exam. Well at least for me anyway, others may have liked it.

i hope 55 ish is an A :/
how did everyone find it ?
i didnt like it one bit

I actually quite liked it, I was glad there wasn't anything with loads of pulleys and weights. I think the locomotive question was fine once you'd realised you had to convert from tonnes into kg, my friend forgot and got acceleration as like 100 ms^-2 :L

I definitely found it more wordy than the past papers I've done though, what with applying a 0 resultant to a situation with a particle and hiker etc.
