# (Solved): Particles A and B are traveling counterclockwise around a circular track at a constant speed of 6 ...

Particles A and B are traveling counterclockwise around a circular track at a constant speed of 6 m/s . At the instant shown the speed of A begins to increase by (at)A=(0.3sA)m/s2 , where sA is in meters. Suppose that r = 7 m . (Figure 1) Figure1 of 1 The particles labeled 'A' and B travel counterclockwise along the same circular path of radius r. Particle B travels along the track counterclockwise from the rightmost point of the path. Particle 'A' travels counterclockwise along the path from the point above and to the left of the center of the path so that the angle between the radii to the initial positions of the particles is 120 degrees. Distances traveled by particles 'A' and B from their initial points are labeled s subscript 'A' and s subscript B, respectively. Part A Determine the distance measured counterclockwise along the track from B to A when t = 1 s . Express your answer to three significant figures and include the appropriate units.
