Asked by Michael

You are standing on the equator of the earth (radius 3960 miles).
a) what is your linear speed in miles per hour?
b) what is the angular speed in radians per hour?

Answered by Steve
speed = distance/time, so

2π*3960mi/24hr = ? mi/hr

2πrad/24hr = ? rad/hr
Answered by shella
2π x 3960 mi/24 hrs = 1036.73
mi/hrs

w=v/r= 1036.73 mi/hrs / 3960 mi

w = 0.262 rad/hrs
