lecture 3:
Cars A and B are traveling around the circular race track. At the instant shown, A has a speed of 60 ft/s and is increasing its speed at the rate of 15 ft/s^2 until it travels for a distance of 110πft, after which it maintains a constant speed. Car B has a speed of 120 ft/s and is decreasing its speed at 16 ft/s2 until it travels a distance of 65πft, after which it maintains a constant speed. Determine the time when they come side by side.
r(A) = 400ft
r(B) = 390ft
