The problem that follow involve straight-line motion. The time t is in seconds unless otherwise stated.

Problem

Let L be a line from the center of the earth to a fixed point on the equator, and let L0 be a fixed reference direction. The figure views the earth from above the north pole.

(a) Is dθ/dt positive or negative? (Remember that the sun rises in the east.)

---

(b) Determine the approximate value of dθ/dt in rad/s and use it to calculate the angle through which the earth rotates in one hour.
