Textbook Question
Chapter 14, Problem 9IP
A 50-kg diver in a full layout position, with a total body radius of gyration with respect to her transverse principal axis equal to 0.45 m, leaves a springboard with an angular velocity of 6 rad/s. What is the diver’s angular velocity when she assumes a tuck position, reducing her radius of gyration to 0.25 m? (Answer: 19.4 rad/s)

The “mean-speed theorem” for finding average velocity under constant acceleration, proposed by the Oxford Calculators, and demonstrated geometrically by Nicole Oresme, is expressed algebraically as:
density = weight/volume
(m1)(v1) = (m2)(v2)
(vm) = 1/2 (v0 + vf)
s = (v0)(t) + 1/2 (a)(t2)
velocity = distance/time
why is the maximum velocity in the michaeli's equation not touching the rectangular hyperbolic curve
The oxygen cost of running on a flat surface at 200 m/min would be about: (hint: pay close attention to units in each answer choice).

- Omar is snorkeling (surface swimming with a tube in his mouth to maintain breathing while his face is in the water). a. The snorkel tube is 35.0 cm in length and 1.4 cm in radius. How does this affect Omar's breathing? Calculate the increase in relative resistance contributed by the snorkel tube. b. What is dead space and how does that affect snorkeling? Explain your answer, assuming the snorkel tube is a round cylinder and cylinder volume is πr²L. How does the snorkel tube affect alveolar ventilation (assume a ventilation rate of 13 breaths/ min, tidal volume of 600 mL, and normal dead space volume of 150 mL.)? If normal alveolar ventilation is 4200 mL/min, how must Omar breathe during snorkeling compared to normal? c. Omar loves snorkeling, but wishes he could go a little deeper. He decides to create a longer snorkel tube to try to achieve this desire. He isn't sure how radius figures in, so he makes two tubes of 80 cm length, one with a 1.6 cm radius and the other with a 2.2 cm…arrow_forwardSolve using Instantaneous Center of Zero Velocityarrow_forwardYou have measured the following data for enzyme X.
