Overall it was good. The bearing angle should be 3 digits there it should be 021. I forgot the 0 -_-

That's what I put, reason for first was that the graph only shows speed so gives no indication of direction. And for the last one was just workings out showing it was 420m.

I thought the paper (Section B specifically) was a touch more difficult than the past papers I've done.

On the question that asked about the resultant from the floor, I use Pythagoras and got 60.1N (I think). Any idea if that's right?

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.

I think i did the same, i had no idea so i guessed that you could use pythag with the friction and the normal reaction, think 60.1 was what i got too, not sure if thats how you do it though
