Chapter 4, Problem 20P
(II) Using focused laser light, optical tweezers can apply a force of about 10 pN to a 1.0-μm diameter polystyrene bead, which has a density about equal to that of water: a volume of 1.0 cm3 has a mass of about 1.0g. Estimate the bead’s acceleration in g’s

Titania, the largest moon of the planet Uranus, has 18the radiusof the earth and 1/1700 the mass of the earth. (a) What is the accelerationdue to gravity at the surface of Titania? (b) What is the average densityof Titania? (This is less than the density of rock, which is one piece ofevidence that Titania is made primarily of ice.)
1) Compute the drag force on a missile 0.6 cm in diameter moving at 250 m/s at low altitude,where the density of air is 1.2 kg/m3. Assume C = 0.8.
assume g= 10m/s^2
One day, you are driving your car down the highway, and you notice that you are driving well over the speed limit. You apply the brakes of the carapplying a variable stopping force, until the car slows down to a rea sonable speed of 22.4 m/s (50 mph)A computer plots the force versus time for the vehicle and then measures the area under the curve. It is found that the area is - 18.950N . The total breaking time was 5.4 s. Given that the combined mass of you and your car 1sm = 1200 kg how fast were you moving before applying the breaks? What is the average force applied by the road to the car during breaking? (Note: 1Ns=1kg* m/s)
