The power of is series combination is Vn^2 times that of a parallel combination.
For series combination :
Req = R + R + R + ............... n times = nR
I = Δv/nr
Power = (Δv/nr)^2 × nr = Δv^2/nr
For parallel combination
1/req = 1/R + 1/R + 1/R +................(n times) = n/R
Req = R/n
Power = Δv/(R/n) = nΔv^2/R
Ratio = Δv^2/nr/n·Δv^2/R = 1/n^2
Hence, power of is series combination is Vn^2 times that of a parallel.

Explanation:
At point B, the velocity speed of the train is as follows.
=
= 26.34 m/s
Now, we will calculate the first derivative of the equation of train.
y =
Now, second derivative of the train is calculated as follows.
Radius of curvature of the train is as follows.
=
= 3808.96 m
Now, we will calculate the normal component of the train as follows.
=
= 0.1822
The magnitude of acceleration of train is calculated as follows.
a =
=
=
Thus, we can conclude that magnitude of the acceleration of the train when it reaches point B, where sAB = 412 m is .
