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:
n =22
Step-by-step explanation:
12-5=7
15-5=10
20-5=15
n-5=17
collect like terms
n=17+5
n=22
Answer:
what are the answers
Step-by-step explanation:
okay the answer is B. y=e^x+3
P= 2(b+2) + 2(b)- it would be 2 (width) plus 2( length)
