Chapter 1, Problem 19P

Suppose that, while lying on a beach near the equator watching the Sun set over a calm ocean, you start a stop watching just as the top of the Sun disappears. You then stand, elevating your eyes by a height H = 1.70 m, and stop the watch when the top of the Sun again disappears. If the elapsed is t = 11.1 s, what is the radius r of earth?

Suppose that, while lying on a beach near the equator of a far-off planet watching the sun set over a calm ocean, you start a stopwatch just as the top of the sun disappears. You then stand, elevating your eyes by a height H = 1.59 m, and stop the watch when the top of the sun again disappears. If the elapsed time is t = 10.4 s, what is the radius r of the planet to two significant figures? Notice that duration of a solar day at the far-off planet is the same that is on Earth. (Hint: See Sample Problem 1-4.) Number Units
A person’s arm rotates around the shoulder (S) and elbow (E) joint axes. The arm has the length a = 9 1/2", the forearm has the length b = 11". The shoulder joint angle is θ = 43°. The elbow joint angle is γ = 21°. a) Compute the Cartesian coordinates of the endpoint H by using a+b. b) Identify the origin of your reference frame.
