I just did a sine wave for the signal
I got 18KN resistant force (P=W/T, W=FxD)
I got 28.1m up the slope (from KE=1/2 x mv^2, equated to PE=mgh to find the height, then trig to find the distance)
The battery was 2 sets of 2 batteries in series, and the sets connected in parallel. So I...
I think I got most of the mechanics out, but I had a stab in the dark on that helipoter one.
The drawings were really good I thought
The multi choice was hard - lots of mechanics questions
WTF was with those batteries? I think I got it but it took some thinking
Some of the short answer...
