Expert Solution
Step 1

To Find :

The normal reaction on the ground and the rate of increase in speed at the instant shown.

Given :

The speed at x=10m is v=4ms.

The mass of skier is m=52kg.

y=30(1-e-0.5x )

Formula :

The radius of curvature can be obtained as,

R=1+dydx23/2d2ydx2

Here R is radius of curvature,
