The answer to the question is two.
Answer:
station A
Step-by-step explanation:
Given data
We are told that she has $85 and she wants to fill only her tank
station A
charges $2.67 per gallon
12 gallons will cost
=12*2.67
=$32.04
station B
charges $2.60 per gallon
12 gallons will cost
=12*2.60
=$31.2
station C
charges $2.62 per gallon
12 gallons will cost
=12*2.62
=$31.44
The cheapest is station A
So, r' (the new r) becomes kr, and h'=h*k,
so V' = pi * (r')^2*h' = pi * (r*k)^2*(h*k) = pi*r^2*h*k^3 = V * k^3

Answer:
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
For part 3
I'm not sure what they mean by "not realistic"
while the initial acceleration is high. the acceleration at t = 1 is zero except that in 'reality' the car would have to be going through a curve to change direction from down to up. That would create very high centripetal acceleration and therefore centripetal forces.
