A velocity field is given by u = 3 y; v = -3 xover the range 0<x<2; 0<y<2
Take the density as 1 and the "depth" (in the z direction) as 1.
a) Validate that this field is incompressibleb) calculate the mass flow rate out through each of the four sides of the box and show that sum of these is 0. c) Plot velocity vectors using Matlabs' quiver function d) Find out and plot the streamlines coming out of the left and bottom boundaries, x=0 and y=0e) Find out the net force exerted on the fluid inside the box by summing momentum flow rates out through each of four sides of the box.

A father (m = 70 kg) and son (m = 45 kg) are standing facing each other on a frozen pond. The son pushes on the father and finds himself moving backward at 3 m/s after they have separated. How fast will the father be moving.
Two forces are applied to a car in an effort to accelerate it. The first force, F1 = 328 N, is applied at an angle α = 35° to the forward dashed line. The second force, F2 = 544 N, is applied at an angle β = 8° to the forward dashed line. (a) What is..
