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?

Consider a u-tube whose arms are open to the atmosphere. now equal volumes of water and light oil (ρ = 49.3 lbm/ft3) are poured from different arms. a person blows from the oil side of the u-tube until the contact surface of the two fluids moves to the bottom of the u-tube, and therefore, the liquid levels in the two arms are the same. if the fluid height in each arm is 30 in, determine the gage pressure exerted by the person on the oil by blowing.
