(a) Two go-karts, A and B, travel around two circular tracks of radius 5 m and 10 m, respectively, each in 10.34 s. Does A or B have the greater acceleration? Which has the greater speed?
(b)If instead the two go-karts travel around the two tracks at the same speed, which has the greater acceleration, A or B? Which takes less time to complete one revolution?
a) a = mv^2/r
which went further in the same amount of time?
b) Which distance is greater?
