what key feature(s) can be easily identified from standard form? Explain how each key feature is related to the rollercoaster. Use specific values in your explanation.

Step-by-step explanation:

Key features

when t = 0

the initial height is 143/3  = 47⅔ ft

initial velocity is -310/3 = -103⅓ ft/s (downward)

initial acceleration is 2(64) = 128 ft/s² (upward)

I would not like to ride this roller coaster!

that's about four times the acceleration of gravity, and it only increases as the car gets to the bottom of the curve at t = 1 s

the answer is 15% decrease

(-5,-28)
