12-138. Two cyclists, A and B, are traveling counterclockwise around a circular track at a constant speed of 8f(t)/(s) at the instant shown. If the speed of A is increased at (a_(t))_(A)=(s_(A))f(t)/(s^(2)), where s_(A) is in feet, determine the distance measured counterclockwise along the track from B to A between the cyclists when t=1s. What is the magnitude of the acceleration of each cyclist at this instant?
Prob. 12-138
The correct answers are d=106ft, aA= 9.88ft/s^2, and aB =1.28ft/s^2. I need help with the work.
