a) Automotive has? 19-545? tab ,- A car maintaining 70 mph crests a large hill as drawn above; if we treated the hill as a fraction of a circular path, the circle's radius would be 135 m. At the apex of the hill, how many.r g's do the passengers experience? :9 d) Proportional reasoning with fluids 40 L (liters) of water flow through a 5 cm diameter pipe per minute. If the pipe widened to 10 cm, what would be the flow volume in the larger end of the pipe? X L/min Same scenario as above: If the water is moving through the 5 cm diameter pipe at 32 cm/s, how fast is it moving through the wider pipe? cm/sConstants & other possibly-useful information: sin(300) = cos(600) = 1/2 (for any 0) sin(450) = cos(450) = 1/ V2 = V2/2 sin(60) = cos(30) = V 3/2 Mass of Earth: ME = 6.0x1024 kg 1 mile = 1609.34 m; 1 mile per hour = 1.61 km/hr = 0.447 m/s = 2688 furlongs per fortnight 1 atm = 1.01x105 Pa Rotational inertia formulas for common shapes: hoop or hollow cylinder: I = MR2 thin rod about center: I = (1/12) ML2 disk or solid cylinder: I = (1/2) MR2 thin rod about end: I = (1/3) ML2 uniform solid sphere: I = (2/5) MR2 point mass a distance r from axis: I = mr2
