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
A reflection over the Y-axis would be the flipped point or set of points across the y axis while still retaining the same distance from the y-axis.

. Solve for standard form.
To find the opposite of 5p²+4, find the opposite of each term inside the bracket.
Combine 7p² and -5p² to get 2p².
Answer:
27. <
28. <
29. =
30. =
Step-by-step explanation:
For absolute value, the value can never be negative unless a negative sign is in front of the absolute value equation. For example |-4| is positive 4 ,but -|-4| is -4. Another way is if you know what multiplying each sign is.
For the fractions, you need to change the fractions to a equal denominator. Hope this helps.
