Cars A and B are traveling respectively at the constant speeds of (vA)0 = 36 km/h and (vB)0 = 20 km/h on an ice-covered road. To avoid overtaking car B, the driver of car A applies his brakes so that his car decelerates at a constant rate of 0.14 ft/s2. Determine the distance d between the cars at which the driver of car A must apply his brakes to just avoid colliding with carB.
