Chapter 8, Problem 70GP(choose chapter or problem)
A 68-kg skier encounters a dip in the snow’s surface that has a circular cross section with a radius of curvature of 12 m. If the skier’s speed at point A in Figure 8–25 is 8.0 m/s, what is the
normal force exerted by the snow on the skier at point B? Ignore frictional forces.

QUESTION:
A 68-kg skier encounters a dip in the snow’s surface that has a circular cross section with a radius of curvature of 12 m. If the skier’s speed at point A in Figure 8–25 is 8.0 m/s, what is the
normal force exerted by the snow on the skier at point B? Ignore frictional forces.
ANSWER:
Step 1 of 4
Here we need to calculate the normal force exerted by the snow on the skier when he is at point B.
In the given case, the skier of mass is with initial speed
when he is at point A. During the journey, he encounters a dip snow’s circular surface with radius
and reaches point. The point B is at height
and point A is at height
.
Given data,
Initial speed
Mass
Radius
Height of point B,
Height of point B,
To find,
Final speed of skier at point B,
Normal force,
