An Escalator At The St. Louis Galleria
y rate = (5/6) feet per second So:
y(t) = (5/6) t feet where t seconds is
variable time and y(t) is vertical y distance as a function of time.
[ y(t) = (5/6) t ] 1. Due to the 30 degree angle hence 30, 60, right angle triangle the vertical y displacement is half of the escalator tread displacement. If it takes t = 19.2 seconds for Point G to travel from Point B to Point E, then Point H will go from Point C to Point E in the same period of time.
Confirm that the rate (speed) in the y direction r = ___________ feet/second.
