7. Let’s compare the typical stopping distances for a car sliding to a stop from an initial speed of 10.0 m/s on a dry horizontal road, an icy horizontal road, and an icy hill. (a) How far does the car take to slide to a stop on a horizontal road if the coefficient of kinetic friction is ?ј = 0.60? (b) What is the stopping distance if the road is covered with ice with ?ј = 0.10? (take g = 9.8 N/kg) [3 mar​
