I got that but a lot of people in my class are saying power of 33. But they may have a made a mistake with R2 instead of R1 so I'm hoping 31

1070? I did mass x velocity to get the force, then did that times sin 55 and added it to his weight, though you might have to had taken it away.

did the same, I did the vertical component of the force due to the hosepipe + the weight to get 1070

Thats what i did and added to get 1070 ish well the rate*velocity to get the force then *sin55 and add the weight at the end.

Ugh I don't know how I found that... I was very very rushed and didn't even finish the last question. Mainly because I found the first one very hard. I loved the space/binary star question, but it took me a while... I just hope I get the A I need, but I'm not expecting it.. onto fpfp I suppose
