Textbook Question
Chapter 26, Problem 37EAP
A typical cell has a layer of negative charge on the inner
surface of the cell wall and a layer of positive charge on the
outside surface, thus making the cell wall a capacitor. What is
the capacitance of a -diameter cell with a 7.0-nm-thick
cell wall whose dielectric constant is 9.0? Because the
cell's diameter is much larger than the wall thickness, it is rea-
sonable to ignore the curvature of the cell and think of it as a
parallel-plate capacitor.

You are working with a movie director and investigating a scene with a cowboy sliding off a tree limb and falling onto the saddle of
a moving horse. The distance of the fall is several meters, and the calculation shows a high probability of injury to the cowboy
from the stunt. Let's look at a simpler situation. Suppose the director asks you to have the cowboy step off a platform 2.55 m off
the ground and land on his feet on the ground. The cowboy keeps his legs straight as he falls, but then bends at the knees as
soon as he touches the ground. This allows the center of mass of his body to move through a distance of 0.660 m before his body
comes to rest. (Center of mass will be formally defined in Linear Momentum and Collisions.) You assume this motion to be under
constant acceleration of the center of mass of his body. To assess the degree of danger to the cowboy in this stunt, you wish to
calculate the average force upward on his body from the ground, as a multiple of the cowboy's…
