On a banked race track, the smallest circular path on which cars can move has a radius of 121 m, while the largest has a radius of 167 m, as the drawing illustrates. The height of the outer wall is 16.4 m. Find (a) the smallest and (b) the largest speed at which cars can move on this track without relying on friction. (a) Number Units (b) Number i UnitsA racetrack has the shape of an inverted cone, as the drawing shows. On this surface the cars race in circles that are parallel to the ground. For a speed of 35.8 m/s, at what value of the distance d should a driver locate his car if he wishes to stay on a circular path without depending on friction? 40,0 140.0 Number i UnitsTwo satellites are in circular orbits around the earth. The orbit for satellite A is at a height of 533 km above the earth's surface, while that for satellite B is at a height of 874 km. Find the orbital speed for (a) satellite A and (b) satellite B.
