Chuck and Jackie stand on separate carts, both of which can slide without friction. The combined mass of Chuck and his car, mcart, is identical to the combined mass of Jackie and her cart. Initially, Chuck and Jackie and their carts are at rest. Chuch then picks up a ball of mass mball and throws it to Jackie, who catches it. Assume that the ball travels in a straight line parallel to the ground (ignore the effect of gravity).After Chuck throws the ball, his speed relative to the ground is vc
. The speed of the thrown ball relative to the ground is vb Jackie catches the ball when it reaches her, and she and her cart begin to move. Jackie's speed relative to the ground after she catches the ball is vj.
When answering the questions in this problem, keep the following in mind:
1. The original mass mcartof Chuck and his cart does not include the mass of the ball.
2. The speed of an object is the magnitude of its velocity. An object's speed will always be a non-negative quantity.
A. Find the relative speed ubetween Chuck and the ball after Chuck has thrown the ball.
B. What is the speed vbof the ball (relative to the ground) while it is in the air?
C. What is Chuck's speed vc(relative to the ground) after he throws the ball?
D. Find Jackie's speed vj(relative to the ground) after she catches the ball in terms of vb.
E. Find Jackie's speed vj(relative to the ground) after she catches the ball in terms of u.

Two horizontal plates with infinite length and width are separated by a distance h in the z direction. the bottom plate is moving at a velocity u. the incompressible fluid trapped between the plates is moving in the positive x-direction with the bottom plate. align gravity with positive z. assume that the flow is fully-developed and laminar. if the systems operates at steady state and the pressure gradient in x-direction can be ignored, do the following: 1. sketch your system 2. identify the coordinate system to be used. 3. show your coordinates and origin point on the sketch. list all your assumptions. 5. apply the continuity equation to your system. nts of navier stokes equations of choice to your system 7. solve the resulting differential equation to obtain the velocity profile within the system make sure to list your boundary conditions. check units of velocity 8. describe the velocity profile you obtain using engineering terminology. sketch that on the same sketch you provided in (1). 9. obtain the equation that describes the volumetric flow rate in the system. check the units.
