Determine the terminal settling velocity in water of a spherical sand particle of 0.5 mm diameter. the density of the sand is 2.65 x 10^3kg/m3, and the viscosity of water at 25 °c is 1.0 x lo^-3kg-m^-1.s^-1. hint: stokes' law is not appropriate.

The bar of prob. 5/82 is repeated here. the ends of the 0.4-m bar remain in contact with their re- spective support surfaces. end b has a velocity of 0.5 m/s and an acceleration of 0.3 m/s2 in the di- rections shown. determine the angular accelera- tion of the bar and the acceleration of end a.
