1. The problem statement, all variables and given/known data At the instant shown, race car A is passing race car B with a relative velocity of 1ft/s. Knowing that the speed of both cars are constant and that the relative acceleration of car A with respect to Car B is 0.9ft/s^2 directed toward the center of curvature, determine the speeds of cars A and B. The diagram is located here: Problem 134 http://www.smccd.net/accounts/enriquez/Engr240Files/Problemset3.pdf Thank you! 2. Relevant equations 3. The attempt at a solution With the relative acceleration being what it is in the j direction, I plugged in 0.9 = vb^2/p - va^2/p and plugged in a 3+Va for vb. That doesnt work. What should I do here? Thanks!
