Question
Automobiles A and B are traveling in adjacent highway lanes and at t = 0 have the positions and speeds shown, where S = 77.1, (VA)O
= 23.3 mi/h, and (VB)o = 36.8 mi/h. Knowing that automobile A has a constant acceleration of 1.72 ft/s2 and that B has a constant
deceleration of 1.12 ft/s2, determine the relative velocity (in mi/h) of B with respect to A at the moment when A overtakes
B. Round off only on the final answer expressed in 3 decimal places.
