W) 7 m/s? A car moving at 35 mph is trying to stop on an icy road. The maximum possible deceleration rate is given by a μ g where g is the gravitational acceleration and μ the coefficient of friction. How long is the car's braking distance? Take-02, which is a reasonable value for this situation. 61 m...

On a cold, icy, winter day, Dr. Roberts was severely injured in a motor vehicle crash on his way to the hospital. He was listed in critical condition for several days, lapsing in and out of a coma. Dr. Roberts finally stabilized and was released home after 2 weeks. With lots of hard work and rehabilitation, Dr. Roberts went back to work after 5 months. Within 2 weeks, his support staff and the hospital personnel started noticing his forgetfulness. He...

A man steps outside one winter day to go to work. His icy driveway is 8.0 m long from top to mailbox, and it slopes downward at 27 degrees from the horizontal. He sets his briefcase on the ice at the top while opening the garage, and the briefcase slides down the driveway. Ignore friction. a) What is its acceleration? b) How many seconds does it take to get halfway to the mailbox? c) How many seconds does it take...

5, Some of the funniest videos on the web involve motorists sliding uncontrollably on icy roads. Here 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 hori- zontal road, and (everyone's favorite) an icy hill. (a) How far does the car take to slide to a stop on a hori- zontal roadi if the coefficient of kinetic friction is = 0.60, which...
