Two technicians are discussing possible reasons for a slow brake pedal return on a hydro-boost equipped vehicle. technician a states that it could be caused by a restriction in the return line from the hydro-boost unit to the power steering reservoir. technician b states that it could be caused by a leak in the return line to the power steering reservoir. which technician is correct?

Awater slide of length l has a vertical drop of h. abby's mass is m. an average friction force of magnitude f opposes her motion. she starts down the slide at initial speed vi. use work-energy ideas to develop an expression for her speed at the bottom of the slide. then evaluate your result using unit analysis and limiting case analysis. express your answer in terms of the variables h, m, l, vi, f and appropriate constants. vf v f

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.)
