Help Pls!!!! Can someone tell me how to do this question: 1. a) A car is travelling at 34.5 mi/h on a horizontal highway. The acceleration of gravity is 9.8 m/s^2. If the coefficient of static friction between road and tires on a rainy day is 0.064, what is the minimum distance in which the car will stop? b) What is the stopping distance when the surface is dry and the coefficient of friction is 0.675. Thanks.
