Acar has a mass of 1500 kg. if the driver applies the brakes while on a gravel road, the maximum friction force that the tires can provide without skidding is about 7000 n.

if the car is moving at 18 m/s, what is the shortest distance in which the car can stop safely?

                            S =34.71 m

Explanation:

M=1500 kg

F=-7000 N

For short and safe distance stop the friction acting should be maximum

                             a(max)=

                                        =

                                         = m/s2

                                  u=18 m/s

Applying equation of motion

                                   v²=u²+2aS

                                   0=

                                    S =34.71 m

the answer is a 3.8cm
