The distance d (in ft) required to stop a car that was traveling at speed v (in mph) before the brakes were applied depends on th amount of friction between the tires and the road and the driver's reaction time. After an accident, a legal team hired an engineering firm to collect data for the stretch of road where the accident occurred. Based on the data, the stopping distance is given by d30.02v²+1.2v. Gaje Snover/Alamy Stock Photo (a) Determine the distance required to stop a car going 30 mph. Round to the nearest foot. (b) Up to what speed could a motorist be traveling and still have adequate stopping distance to avoid hitting a deer 383 ft away? Round to the nearest mile per hour.
