A somewhat idealized graph of the speed of the blood in the ascending aorta during one beat of the heart appears as in Figure P2.16. Figure P2.16 a. Approximately how far, in cm, does the blood move during one beat? b. Assume similar data for the motion of the blood in your aorta, and make a rough estimate of the distance from your heart to your brain. Estimate how many beats of the heart it takes for blood to travel from your heart to your brain.

A frustrated office worker throws his laptop out of his business's high-
rise office building. The height, h, in meters of the laptop above the ground at t
seconds can be modelled by h(t) = 125-5t².
a. Determine the average rate of change between the third and fourth second
of the laptop's flight.
b. Estimate the rate at which the laptop hits the ground.
According to Timothy Treadwell in 2001 "Now, the bears I live with average, the
males are on average twelve hundred pounds. They're the largest bears in the
world and they've been clocked at 41 [mph] and they've run a hundred meter
dash in 5.85 seconds which human on stimulants doesn't even approach.
a. Compute the speed of a grizzly bear using Mr. Treadwell's hundred-meter
statement.
b. Compute the momentum of a grizzly bear using the speed you calculated in
part a. and the average mass stated by Mr. Treadwell.
c. How fast would a 250 lb man have to run to have the same momentum you
calculated in part b?
d. How fast would a 4000 lb car have to drive to have the same momentum you
calculated in part b?
