An advertisement claims that a car can stop on a dime. If the car is 850 kg and is traveling at 45.0 km/h, what is the magnitude of the net force needed to stop in the distance equal to the diameter of a dime (1.8 cm)

Net force on the car will be      

Explanation:

We have given mass of the car m = 850 kg

Initial velocity of the car u = 45 km/hr

As the car finally stops so final velocity of car v = 0 m/sec

Distance travel for stooping of car s = 1.8 cm = 0.018 m

From third equation of motion

So

So magnitude if acceleration will be

So net force on the car

So net force on the car will be

568.98

explanation:

its math
