1.If the average length of a vehicle is 15 ft and the average space between consecutive vehicles waiting to be served is 3 ft, what is the minimum length for the off-ramp to provide storage for all exiting vehicles 80 percent of the time?
2.Collars A and B are connected by a 25 in long wire and can slide freely on frictionless rods. If a 60 lb force Q is applied to B determine a) tension in wire when (black) x = 9 in and b) corresponding mag of force P required to maintain equilibrium of system
3.Determine initial velocity if a ball from rest is kicked at an initial angle of 58.3 deg, and travels in the x direction 6m and 3m in y direction. take gravity into account.
4.A fireman is standing on a hoist and sprays water at a fire. the fire is 35 ft in the x direction and 20ft downward in the y direction. the water flows at 65 ft/s. determine two possible angles theta at which this can be done. assume the angle below the horizontal is positive.
