A jet of water of cross-section A and density ρ moves horizontally at an inertial velocity v0 and hits a block of mass M, as in Figure 6.42. Assume that the collision is inelastic (i.e., the water leaves with a zero horizontal component of velocity relative to the block) and that there is a coefficient of friction μ between the block and the surface on which it slides. Find the final speed vƒ of the block.
Prepare shadow maps for point P on the sun-path diagrams for 35°N and 40°N for the three geometries shown in (a), (b), and (c) below. Determine the hours of shading that occur each month.
