I though it was really easy compared with past papers. Did everyone get 'k' as 20 N per m for the final question? Also did you get approx 116 for the final velocity of the cannonball?

I thought it was easy yes but only us retakes doing it so very high UMS... I got both of those!

Did anyone understand how to find the velocity of the plane on the last part of question 1?
You use P=Fv then rearrange to work out v. Power was 40kW and the force was Tcos36 so you use your value of T then divide the two to get v. Hope this helps

damm i knew i'd forgotten an equation... ah well.. thanks

Wasn't the force 800N? Or is that Tcos36 and I'm just being silly😂
