Two cars travel westward along a straight
highway, one at a constant velocity of
96 km/h, and the other at a constant velocity
of 113 km/h.
assuming that both cars start at the same
point, how much sooner does the faster car
arrive at a destination 24 km away?
how far must the cars travel for the faster car
to arrive 16 min before the slower car?
answer in units of km.

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)
