Interesting stuff:So lets say Stealth accelerates to 80mph in 1.75 seconds. An empty train weighs 10,000 kg and the weight of the average rider is 70 kg.A train carries 20 passengers, so the overall weight of the fully loaded train is (70X20)+10,000 Which equals 11,400 kg80mph = 1/45 miles/second = 35.7632m/sTherefore the distance travelled by the train in these first 1.75 seconds is 1/2(35.7632+0)1.75 Which equals 31m (ish).a=(v-u)/t So the Acceleration is (35.7632-0)/1.75 Which equals 20.4m/s (ish)Force=mass X acceleration, so F=11,400 X 20.4 Which equals 232971N A lot of force is required to launch Stealth!The work needed to be done to create this force = Force X Distance Therefore work done= 232971 X 31 Work=7290337JPower=Joules/seconds So the power is Work/time which equals 7290337/1.75 This equals 4165907W (ish)Estimating that each household contains 40 lightbulbs, the power it takes Stealth to launch could light around 3,500 houses.BAM.Two train operation, or saving the environment? Slightly.I SAY TWO TRAINS.
