Imagine that you place a little pipette, length 1 cm on
acentrifuge with radius r=70 cm. inside the pippette, there isa
viscous liquid, with viscosity 20 times more than water. inthis
liquid there is a cell of size 1.5 micrometer. the onlyforce that
can provide centripetal acceleartion to the cell is thefriction
force which will develop if the cell moves through theliqid. find
terminal velocity fo the cell assuming centrifugerotates at 1500
rpm. assume cell density is 2 % higher thanwater.

One hazard of space travel is debris left by previous missions. there are several thousand masses large enough to detect by radar orbiting the earth, but there are far greater numbers of very small masses such as flakes of paint. calculate the force exerted by a 0.110 mg chip of paint that strikes a space shuttle window at a relative speed of 5.00 ✕ 103 m/s and sticks, given the collision lasts 6.00 ✕ 10-8 s. such a collision chipped the window of the ill-fated challenger in june 1983, causing $50,000 of damage.
