An engineer is setting a speed limit on a road. She wants a car to be able to
stop in 147ft and knows that the maximum rate at which a car can safely
brake is 20.0ft/s?
What initial speed (in given units) will allow the car to come a stop at the stop
sign when braking with this acceleration?
mph
Could a car traveling 60mph come to a stop before the stop sign?
