Question

Racing cars A and B are traveling on circular portions of a race track with the speeds indicated in the figure. At the instant shown, the speed of A is decreasing at the rate of 7 m/s2, and the speed of B is increasing at the rate of 2 m/s2. For the positions shown, determine the values of r, 0, r, ï, and ë with respect to the observer at A, where r and are measured relative to a longitudinal axis fixed to car A as indicated in the figure. 250 m 162 km/h 450 B e 400 m 300 m A 300 144 km/h 700 m

(1) Racing cars A and B are traveling on circular portions of a race track with the speeds indicated in the
figure. At the instant shown, the speed of A is decreasing at the rate of 7 m/s?, and the speed of B is
increasing at the rate of 2 m/s. For the positions shown, determine the values of r, 6, †, è̟, * and ö with
respect to the observer at A, where rand e are measured relative to a longitudinal axis fixed to car A as
indicated in the figure.
