Problem a car has a mass of 1500 kg if the driver applies, Ask an Expert

Academics

Problem: A car 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.

Problem: If the car is moving at 29 m/s, what is the shortest distance in which the car can stop safely?

I don't know how to get that answer for the above problem. Please help! Thanks.
