A multilane highway, with three lanes in each direction, operates at maximum level of service D conditions during the peak hour with an observed speed of 48.0 mi/h (with 3690 veh/h observed). The highway is on rolling terrain and the traffic stream consists of cars and some percentage of heavy vehicles. The peak-hour factor is 0.85. If heavy vehicles were banned from the highway and car traffic remained the same, what would be the LOS

This problem has been solved! see the answera non-uniform fire escape ladder is 6.0m long whenextended to the icy alley below. it is held at the top by africtionless pivot, and there is neglibible frictional force fromthe icy surface at the bottom. the ladder weighs 250n, and it'scenter of gravity is 2.0m along the ladder from the bottom. amother and child of total weight 750n are on the ladder 1.5m fromthe pivot. the ladder makes an angle θ with the horizontal.find the magnitude and direction ofa) the force exerted by the icy alley on the ladderb) the force exerted by the ladder on the pivotc) do your answers in part a and b depend on the angle?

Amass weighing 24 pounds, attached to the end of a spring, stretches it 4 inches. initially, the mass is released from rest from a point 8 inches below the equilibrium position. find the equation of motion. (use g = 32 ft/s2 for the acceleration due to gravity.)
