Pls helppp As you move the trash can to barricade the school door you hear footsteps coming from inside the school. They seem to be coming from the lunchroom. The distance to the lunchroom is 300 m and the time it takes you to get there is 12 seconds. What is the speed you are traveling at?

Onsider a u-tube whose arms are open to the atmosphere. now, equal volumes of water (ρ = 62.4 lbm/ft3) 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 thus the liquid levels in the two arms are the same. if the fluid height in each arm is 31 in, determine the gage pressure the person exerts on the oil by blowing. (round the final answer to three decimal places.)
