Question: As the earth rotates, what is the speed of a physics student in Miami, Florida, at latitude 26degrees Ignore the revolution of the earth around the sun. The radius of the earth is 6400 km.
Question 1: What is the speed of a physics student in Fairbanks, Alaska, at latitude 65?
Please give me an explanation for above question.
John carries one heavy box and kicks the other box so that it slides for a little bit and then stops, and he continues this until he reaches his destination. His kicks to the box have an acceleration of magnitude 4m/s^2. What is the coefficient of ki..
