Answer:
therefore normal reaction on the driver from the seat when the car passes through the bottom of the valley= 1520.55 N
Explanation:
let speed be v
at top of hill
mg-N = mv^2/R ( N=0 at the top of the hill)
==> mg=mv^2/R
at bottom
N-mg=mv^2/R
therefore,
N = 2mg = 2*77.8*9.81= 1520.55 N
therefore normal reaction on the driver from the seat when the car passes through the bottom of the valley= 1520.55 N
