If the speed of an object in uniform circular motion is tripled and the radial distance remains constant, then the magnitude of the centripital acceleration increases by what factor?
The rotor of an ultracentrifuge rotates at a frequency of 50,000 rpm. A particle at the top of the test tube is 6.00 cm from the rotation axis. Calculate the centripetal ( or normal or radial) acceleration.
An astronaut is rotated in a horizontal centrifuge at a radius of 5.6 m. How many revolutions per minute are required to produce if the centripetal acceleration has a magnitude of 5.3g? ( g is the gravitational acceleration, g=9.80 m/s2. Your result must include one digit after the decimal point. Maximum of 5% of error is accepted in your answer. Take π=3.14)
