Two cars that have the same mass are moving around a circular track at the same constant speed?
The track is perfectly level. If car 1 is at the inner edge of the track and car 2 is at the outer edge, then
1) the frictional force on car 1 is less than the frictional force on car 2.
2) the frictional force on car 1 is greater than the frictional force on car
3) the frictional forces on both cars are equal and greater than zero.
4) the frictional forces on both cars are zero.
…none of the answers… “they” are effected by centrifugal force
