Question Details: PLEASE BE EXPLICIT WTH YOUR ANSWEr, display allyour thoughts to let me visualize The earth's radius is about 4000 miles. Kampala, the capital ofUganda, and Singapore are both nearly on the equator. The distancebetween them is 5000 miles.
1.Through what angle do you turn, relative to the earth, if you flyfrom Kampala to Singapore? Give your answer in degrees and then inradians
2.The flight from Kampala to Singapore takes 9 hours. What is theplane's angular velocity relative to the earth? Question Details: PLEASE BE EXPLICIT WTH YOUR ANSWEr, display allyour thoughts to let me visualize

Explanation / Answer

circumference of Earth = 2 R = 2 * 4000 =    25133 miles .     fraction of circumference youtravel = 5000 / 25133 =  0.19894   .     angle in degrees = 0.19894 *360 =    71.62 degrees .    angle in radians =   0.19894 *2 =      1.25 radians .    angular speed = angle / time = 1.25 radians / 32400 seconds =   3.858 x10-5 rad/s
