Question

Two automobiles A and B are approaching each other in adjacent highway lanes. At t = 0, A and B are 3200 ft apart, their speeds are v_A = 66 mi/h and v_B = 39 mi/h, and they are at points P and Q, respectively. A passes point Q 40 s after B was there and B passes point P 42 s after A was there.

Determine the uniform accelerations of A and B. (You must provide an answer before moving on to the next part.)

The uniform acceleration of A is – ____ft/s².

The uniform acceleration of B is ____ft/s².
