Random applied engineering type subject 101 Q: As above. A: Severely breaks the laws of physics. Watts reqiuired =3D vertical m/s x mass x g Or kg mass x m/S vertical ascent rate x 10 =3D Watts / Watt /watts / watt / Wazzup? For 2200 Watts available and 1100 kg+ mass. P =3D 10.V.m V =3D {P/(10.m) =3D 2200 /10/1100 =3D 0.2 ,m/s vertical ascent takes ALL the power, before you even start with windage! 2. ... 30 degrees ... Unless this was in Christchurch NZ, and the road is now 10+ x longer than it was when I last drove up and down it (SCARY!!!) ..then that angle is wrong. Given the above calculation, very very very wrong. Conclusion: Must have a magna whatshisface installed or be made by De Lorea= n.
