Chapter 1.1, Problem LC

(a)

To determine

To calculate: The power expenditure of each runner whose masses are 60kg, 65kg and 70kg, running at 400m/min.

(b)

To determine

Whether the power expenditure increase or decrease as the mass of the runner increases with constant velocity.

(c)

To determine

To calculate: The velocity of each runner whose masses are 80 kg, 84kg and 90 kg, expending power at $P=38.7\text{ kcal/min}$.

(D)

To determine

Whether the velocity increases or decreases as the mass of the runner increases with constant power expenditure.

(e)

To determine

To calculate: The velocity of a 50 kg runner expending power at same rate while carrying 2 kg extra weight and being trained at velocity 480 m/min.

(f)

To determine

The reason for the runners to carry extra weight while being trained.

(g)

To determine

To graph: Power expenditure versus mass of a runner with velocity fixed at 400 m/min and velocity versus mass of a runner with fixed power expenditure at 40 kcal/min with the use of computer.
