A spiral transition curve is used on railroads to connect a straight portion of the track
with a curved portion. (Figure 1)
Part A
v = v₁ft/s
600 ft
y = (106) x³
If the spiral is defined by the equation y = (106)³, where x and y are in feet, determine the magnitude of the acceleration of a train engine moving with a constant speed of v₁ = 30 ft/s when it is at point
x = 600 ft.
