Consider a 2550 lb automobile clocked by law‑enforcement radar at a speed of 85.5 mph (miles per hour). If the position of the car is known to within 5.0 ft at the time of the measurement, what is the uncertainty in the velocity of the car?
Δ𝑣≥ (fill in answer) mph
If the speed limit is 75 mph, could the driver of the car reasonably evade a speeding ticket by invoking the Heisenberg uncertainty principle?

No, physics. If you can't figure that out, learn to read a tape measure.
