You are considering purchasing winter tires for the upcoming winter season. After some research, you discover that your all-season tires offer a coefficient of static friction of about u1= 0.21 on snowy road, while the winter tires offer a coefficient of static friction of about u2= 0.33. Given a reaction time of to= 1.1 s, an initial speed of vo= 85 km/h, How much shorter is the stopping distance when you change to the winter tires?
