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

mv

=
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

Dividing fractions is easy as pie, flip the second one over then multiply
Answer:
30 minutes to the park
Step-by-step explanation:
12/2 = 6 min per mile
6 x 5 = 30 mins for 5 miles
the first step Andre made was
2x+6=3x-8
or, -x+6=-8
And the first step Diego made was
2x+6=3x-8
or, +6=3x-2x
or, 6=x-8
