i. Based on the above equation for Fair, derive an equation for the system's constant terminal speed u, in terms
of r, C, physical constants, and other relevant quantities that can be measured with equipment usually found in
a school physics laboratory, as appropriate. Assume the mass of the parachute is negligible and that the only
nonnegligible forces acting on a block-parachute system are the block's weight mgg and the force of air
resistance Fair-
Fair
V=
Cr
ii. Indicate below what quantities could be measured and then graphed to determine whether the equation
derived in part (c)(i) correctly relates the parachute's radius and the terminal speed of the block-parachute
system.
