svlad2 [7]

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
