Problem 2.841 Cars A and B are traveling at V 72 mph and va 67 mph, respectively, when the driver of car B applies the brakes abruptly, causing the car to slide to a stop. The driver of car A takes 1.5s to react to the situation and applies the brakes in turn, causing car A to slide as well. If A and B slide with equal accelerations, i.e., SA = -g, where p = 0.83 is the kinetic friction coefficient and g is the acceleration of gravity, compute the minimum distance ď between A and B at the time B starts sliding to avoid a collision.

Question
Problem 2.841
Cars A and B are traveling at V 72 mph and va
67 mph,
respectively, when the driver of car B applies the brakes abruptly,
causing the car to slide to a stop. The driver of car A takes 1.5s to
react to the situation and applies the brakes in turn, causing car A to
slide as well. If A and B slide with equal accelerations, i.e., SA
= -g, where p = 0.83 is the kinetic friction coefficient
and g is the acceleration of gravity, compute the minimum distance
ď between A and B at the time B starts sliding to avoid a collision.
