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

mv

=

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
Answer:
28p^2+22p-30
Step-by-step explanation:
I'm a genius
All you have to do is add up all the numbers and divide by the amount of numbers there are so in this case 4
Well 19 would be 399 and for 20. the discount is 12.87 and the price of it after the discount is 26.13
