Answer:
The shanghai maglev train is capable of reaching speeds of up to 217.48 in mph
217.48 mph
Explanation:
Tbar = Tension of the Light Bar
Twire = Tension of the Wire
Newton First Law About Force :
Fx = 0
Tbar cos 45° - Twire cos 25° = 0
Twire = 0.78 Tbar ... (i)
Fy = 0
Tbar sin 45° - Twire sin 25° - 1 = 0 ... (ii)
Subtitute (i) into (ii) :
Tbar sin 45° - 0.78 Tbar sin 25° - 1 = 0
Tbar = 2.563 kN ... (iii)
Subtitute (iii) into (i) :
Twire = 0.78 (2.563)
Twire = 1.999 kN
I would say all of them but if I had to choose one I would say the days would get shorter because if earth began to spin faster then the sun would only be out for a couple of hrs and we would mostly see night than day
