Textbook Question
Chapter 11, Problem 5IP
The angular velocity of a runner’s thigh changes from 3 rad/s to 2.7 rad/s during a 0.5 s time period. What has been the average angular acceleration of the thigh? (Answer: −0.6 rad/s2, −34.4 deg/s2)

The “mean-speed theorem” for calculating average velocity under constant acceleration, developed by Thomas Bradwardine and the Mertonian Calculators at Oxford University, is expressed algebraically as:
density = weight/volume
(m1)(v1) = (m2)(v2)
C. (vm) = 1/2 (v0 + vf)
s = (v0)(t) + 1/2 (a)(t2)
velocity = distance/time
Using the Michaelis-Mentan graph pictured (graphing initial velocity and PNPP concentration), identify Vmax and Km as well as possible. Then, using the Lineweaver-Burk graph (graphing 1/Vo and 1 / PNPP concentration), label the reciprocals of Vmax and Km on the graph and use them to calculate Km and Vmax.
The following graph is simulated (but realistic) data from a VO₂max trial of a human athlete running (no
gait changes). Estimate and label the following variables:
VO2 (ml/kg/min)
1. VO₂max
2. Incremental cost of locomotion
3. Maximum aerobic speed
4. RMR + postural costs
