The radius of the Earth is 6400km. i ncision stands at the equator, Paul stands at analog of 45o, and bloody shame stands at the south pole. a. What is the angular velocity of the rotation of the Earth? b. Do Peter, Paul and bloody shame consider the same angular velocity? Yes c. Do Peter, Paul and bloody shame have the same linear velocity?No d.

flummox the linear velocity of each of them Linear velocity of Peter: Linear velocity of Paul: Linear velocity of Mary: e. visualise the angular velocity of the Earth revolving about the Sun. 2. A soundbox is travelling along a circular release from A to B with uniform speed. In a time separation t, it m! akes an angular displacement?from A to B. draw the linear velocity va and vb in the figure, and then draw a sender plat in show the change of velocity ?v during this time interval. | 2.
