At its ames research center, nasa uses its large "20-g" centrifuge to test the effects of very large accelerations ("hypergravity") on test pilots and astronauts. in this device, an arm 8.84 m long rotates about one end in a horizontal plane, and the astronaut is strapped in at the other end. suppose that he is aligned along the arm with his head at the outermost end. the maximum sustained acceleration to which humans are subjected in this machine is typically 12.5 g. how fast must the astronaut's head be moving to experience the maximum acceleration?

After a big snowfall, you take your favorite rocket-powered sled out to a wide field. the field is 195 m across, and you know that your sled accelerates at a rate of 3.65 m/s2 when the rocket is on. how much time will it take the sled to cross the field starting from rest, assuming the rocket is on the whole time?
