A car is traveling along a road at a uniform velocity when at time zero the driver recognizes a hazard. At a moment 0.8 seconds later the driver brakes her vehicle , resulting in her vehicle sliding 90 ft in the same direction, at which time it strikes another stationary vehicle at 25 mph. The road surface is dry with a coefficient of friction of 0.75. The driver was traveling on a rural highway having a speed limit of 55 mph. Was she exceeding the speed limit? (Note: 5,280 ft = 1 mile, and g = 32.2 ft/s2)
