    Find the required angular speed, ω, of an ultracentrifuge for the radial acceleration of a point 2.00cm from the axis to equal 6.00×105 g (where g is the acceleration due to gravity).

    Calculate the acceleration of a car that is travelling at a constant speed of 100 km per hour on a straight road. The radius R of the Earth is 6370 km. Why do we not feel this acceleration?
