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.
An observer, whose eyes are 1.99 m above the ground, is standing 35.0 m away from a tree. The ground is level, and the tree is growing perpendicular to it. The observer's line of sight with the treetop makes an angle of 23.0° above the horizontal. Ho..

Two ants race across a table 56 cm long. One travels at 4.5cm/s and the other at 2cm/s. When the first one crosses the finish line how far behind is the second one.
What is the total mass of the reagents used in the combustion throughout the 30 days . The ball makes 17 oscillations in 16 seconds. What is it the mass of the ball.
A 9300 kg boxcar travelling at 23 m/s strikes a second boxcar at rest. The two stick together and move off with a speed of 15 m/s. What is the mass of the second car.
A gun shoots bullets that leave the muzzle with a speed of 336 m/s. If a bullet is to hit a target 136 m away at the level of the muzzle, the gun has to be aimed at a point above the target. How far above the target is this point.
The kinetic friction force between surface and disk slows down its linear motion while at the same time making the disk spin on its axis at an accelerating rate. Finally, the disk's rotation catches up with its linear motion, and disk begins to roll ..
Drag race tires in contact with an asphalt surface have an extremely high coefficient of static friction. Assuming a constant acceleration and no slipping of tires, estimation the coefficient of static friction needed for a drag racer to cover 1.0 km..
