Yes, all of these could be applied to a roller coaster.
Answer:
Option C is correct
Explanation:
"The time is determined by the vertical distance. The formula is sqr(2d/a) = t. There still is no acceleration in the horizontal direction."
For the first drive
d = d
t = sqr(2d/a)
r = v
For the Second drive
d = ??
t = sqr(2d/a)
r = 2v
Since the times are same, equate the results.
t = d/v = d1/2v
v*d1 = 2v*d The v's cancel because they are related.
d1 = 2d.
You go twice as far as you did before.
