Alarge cube has a mass of 25kg. it is being acclerated
acrossa honzontial frictionless surface by a horizontal force. a
smallcube with a mass of 4kg is in contact with the front of
thelareg cube and will slide downward unless the horizontal forceis
sufficiently large. the coefficient of static friction betweenthe
two cubes is 0.71. what is the smallest magnitude that
thehorizontal force can have in order to keep the small cube
fromsliding downward?

The ultracentrifuge is an important tool for separating and analyzing proteins. because of the enormous centripetal accelerations, the centrifuge must be carefully balanced, with each sample matched by a sample of identical mass on the opposite side. any difference in the masses of opposing samples creates a net force on the shaft of the rotor, potentially leading to a catastrophic failure of the apparatus. suppose a scientist makes a slight error in sample preparation and one sample has a mass 10 mg larger than the opposing sample. if the samples are 12 cm from the axis of the rotor and the ultracentrifuge spins at 70,000 rpm, what is the magnitude of the net force on the rotor due to the unbalanced samples? ( be thorough on your answer)
