It would be B. because the rise over run is 31.25 over 5 which is divided to 6.25 which is rounded to 6.3
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=

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

⇒u= √2 v
therefore, safe speed for the larger radius track u= √2 v
Answer:
5+3(4-2)
5+3x2
5+6
11
the answer is 11
Step-by-step explanation:
Answer:
62
Step-by-step explanation:
another way to write this is
x - 12 = 50
the answer is 62
62 - 12 = 50
