On a trip to Edmonton, Rob travels at 100km/h(N) for 2.00h and stops for 15.0 min in Red Deer for a coffee. While sipping his coffee he realizes that his Flame's flag blew off his car so he drives back to Calgary to find it. After 30.0 min of driving 110km/h(S) he sees it, turns around and then resumes his trip to Edmonton at 140km/h(N) and arrives 1.25h later. a) what distance did he travel?
b) what is his displacement?
c) What is Rob's average speed?
d) What is Rob's average velocity?

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.
