CP? An advertisement claims that a particular automobile can “stop on a dime.” What net force would be necessary to stop a 850-kg automobile traveling initially at 45.0 km/h in a distance equal to the diameter of a dime, 1.8 cm?

Solution 40P In this problem we will use the formula v = u + 2as To calculate the required acceleration. Step 1 In the given problem we have u = 45.0 km/h = (45.0 km/h)(1000 m/= 12.25 m/s (3600 s/h) v = 0 m/s s = 1.8 cm = 0.018 m
