Step 1: Develop an equation that expresses how the radius changes over time and calculate the length of the radius at 3 seconds. Step 2: Apply conservation of angular momentum to calculate the car's velocity in the tangential direction at 3 seconds. Step 3: Since the car's velocity in the normal direction is already given as 0.5 ft/s we can calculate the magnitude of the car's velocity. ANS = 4.6 ft/s
