The earth's radius is 6.37×106m; it rotates once every 24 hours.

a. What is the earth's angular speed?

b. Viewed from a point above the north pole, is the angular velocity positive or negative?

c. What is the speed of a point on the equator?

d. What is the speed of a point on the earth's surface halfway between the equator and the pole?

(Hint: What is the radius of the circle in which the point moves?)

Earth rotates on its axis once every 24 hours, so that objects onits surface execute uniform circular motion about the axis with aperiod of 24 hours. Consider only the effect of this rotation onthe person on the surface. (Ignore Earth's orbital motion about theSun.)

(a) What is the speed and what is the magnitude of the accelerationof a person standing on the equator?
v = m/s
a = m/s2

b)Express the magnitude of this acceleration as a percentage ofg.
%

(c) What is the direction of the acceleration vector?

is it away from the center of Earth or directly at the center ofEarth


(d) What is the speed and what is the magnitude of the accelerationof a person standing on the surface at 35°N latitude?
v = m/s
a = m/s2

(e) What is the angle between the direction of the acceleration ofthe person at 35°N and the direction of the acceleration of theperson at the equator if both persons are at the samelongitude?

13.37 • The acceleration due to gravity at the north pole of Neptune is approximately 11.2 m/s². Neptune has mass 1.02 X 1026 kg and radius 2.46 X 104 km and rotates once around its axis in about 16 h. (a) What is the gravitational force on a 3.00-kg object at the north pole of Neptune? (b) What is the apparent weight of this same object at Neptune's equator? (Note that Neptune's "surface" is gaseous, not solid, so it is impossible to stand on it.)
