Some time later at kmet, the surface wind (horizontal) pattern is observed to follow this relationship, where a is positive. u= -ax v=-ay a) sketch the horizontal flow at the surface. b) calculate the divergence of the horizontal flow. is this flow convergent, divergent, or neither? c) assuming the surface near kmet is smooth and flat, derive a formula for vertical velocity w as a function of height 2. hint: use the continuity equation for an incompressible fluid of constant density.

Two manned satellites approaching one another at a relative speed of 0.550 m/s intend to dock. the first has a mass of 2.50 ✕ 103 kg, and the second a mass of 7.50 ✕ 103 kg. assume that the positive direction is directed from the second satellite towards the first satellite. (a) calculate the final velocity after docking, in the frame of reference in which the first satellite was originally at rest.(b) what is the loss of kinetic energy in this inelastic collision? (c) repeat both parts, in the frame of reference in which the second satellite was originally at rest. final velocity(d) loss of kinetic energy = ?
