I think 12 might be the second one, I'm not sure though!
Answer:
Answer:
safe speed for the larger radius track u= √2 v
Explanation:
The sum of the forces on either side is the same, the only difference is the radius of curvature and speed.
Also given that r_1= smaller radius
r_2= larger radius curve
r_2= 2r_1..............i
let u be the speed of larger radius curve
now, \sum F = \frac{mv^2}{r_1} =\frac{mu^2}{r_2}∑F=
r

mu

................ii
form i and ii we can write
v^2= \frac{1}{2} u^2v

=

u

⇒u= √2 v
therefore, safe speed for the larger radius track u= √2 v

Step-by-step explanation:
Answer:
236,859 people visited the water park the year it opened.
Step-by-step explanation:
426,731 - 102,865= 323,866 the amount of people that visited last year
323,866 - 87,007 = 236,859 the amount of people that visited the water park the year it opened
