- A centrifuge is a device in which a small container of material is rotated at a high speed on a circular path. Such a device is used in medical laboratories, for instance, to cause the more dense red blood cells to settle through the less dense blood serum and collect at the bottom of the container. Suppose the centripetal acceleration of the sample is 3.94 x 103 times as large as the acceleration due to gravity. How many revolutions per minute is the sample making, if it is located at a radius of 3.61 cm from the axis of rotation?Compute the Moon's centripetal acceleration in its orbit around the Earth. Recall that the Moon orbits the Earth every 28.0 days and that it is about 240000 miles from the Earth. What force causes this acceleration? Please first report the answer using symbolic algebra and then the numerical value. Be sure to convert to SI units.In the first scene of the 1981 movie Raiders of the Lost Ark, archaeologist Indiana Jones inadvertently trips a booby trap and is chased out of a cave by a large spherical rolling stone (you can find the scene on YouTube). If the stone is rolling at 15 mi/h (about as fast as a normal human can run) what minimum vertical distance must it have rolled down before confronting Jones?

Determine the magnitude of the acceleration of the system? If initially mA is at rest 1.250 m from the edge of the table, how long does it take to reach the edge of the table if the system is allowed to move freely? If mB = 1.0 kg, how large must mA be if the acceleration of the system is to be kept at g100?

(c) How long does the coin take to reach the compartment ceiling, 2.20 m above the knee? In unit-vector notation, what are (d) the actual force on the coin and (e) the apparent force according to the customer’s measure of the coin’s acceleration?In a laboratory test of tolerance for high acceleration, a pilot is swung in a circle 15.0 m in diameter. It is found that the pilot blacks out when he is spun at 30.6 rpm (rev/min). At what acceleration (in SI units) does the pilot black out? acceleration: 77.01 m/s? Express this acceleration in terms of a multiple of g. acceleration as a multiple of g: 7.858 If you want to decrease the acceleration by 22.0% without changing the diameter of the circle, by what percent must you change the time for the pilot to make one circle? percent of time change:
- Say that an object of mass is pushed by a system of two radial Forces and moves with a constant speed V In a circle. Which of the following relations are true about this motion? A) The acceleration of the system is zero because the speed is constant B) The object will experience a net centrifugal force that will tend to throw the mass out of the circle C) The object will experience a net centripetal force that will tend to keep the mask on the circle. D) F1-F2=mv^2/r E) Only (c) and (d) are trueThree cars are driving at 22 m/s along the road. Car B is at the bottom of the hill and car C is at hte top. Both hills have a 220 m radius of curvature.
