Assuming the earth to be a perfect shere with a diameter of 8000 miles, find the angular velocity and linear speed of a point at the equator.
.
Since the earth rotates about it's axis once every 24 hours...
.
The "linear speed" is:
(8000 miles)/(24 hours)
333.33 miles/hr
.
The "angular speed" is:
(360 degrees)/(24 hours)
15 deg/hr
