1. 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.

2. What is the speed of a physics student in Fairbanks, Alaska, at latitude 65??

Solutions

Expert Solution

1. Angular speed of earth=2?/[24*3600]=7.272*10-5

                Now, speed of student= angular speed*radius*cos (latitude)

                                                                =7.272*10-5*6400*103*cos26

                                                                =418.3 m/s

2. Speed at Fairbanks=7.272*10-5*6400*103*cos65

                                =196.7 m/s

A student on a piano stool rotates freely with an angular speed of 3.05 rev/s . The student holds a 1.25 kg mass in each outstretched arm, 0.749 m from the axis of rotation. The combined moment of inertia of the student and the stool, ignoring the two masses, is 5.53 kg⋅m2 , a value that remains constant. Part A As the student pulls his arms inward, his angular speed increases to 3.65 rev/s . How far are the masses...

Nate the Skate was an avid physics student whose main non-physics interest in life was high-speed skateboarding. In particular, Nate would often don a protective suit of Bounce-Tex, which he invented, and after working up a high speed on his skateboard, would collide with some object. In this way, he got a gut feel for the physical properties of collisions and succeeded in combining his two passions." On one occasion, the Skate, with a mass of 115 kg, including his...
