You testify as an expert witness in a case involving an accident in which car A slid into the rear of car B, which was stopped at a red light along a road headed down a hill (see the figure). You find that the slope of the hill is = 11.0°, that the cars were separated by distance d = 24.0 m when the driver of car A put the car into a slide (it lacked any automatic anti-brake-lock system), and that the speed of car A at the onset of braking was vo 17.0 m/s. With what speed did car A hit car B if the coefficient of kinetic friction was (a) 0.580 (dry road surface) and (b) 0.100 (road surface covered with wet leaves)? (a) Number (b) Number i ! Units m/s !

The brakes on a big truck fail and it is forced to use a runaway truck lane. The lane is perfectly horizontal, and full of deep gravel, creating a coefficient of kinetic friction between the truck and the gravel of 0.80. The truck enters the lane at moving 35 m/s (about 80 mph). How far does the truck travel before it stops?
A city is trying to determine the speed limit for a given stretch of road. If a stop sign is visible from 62.0m on a straight, horizontal stretch of road and the coefficient of static friction between the road and the tires of a car is 0.525 then what is the maximum speed for a car in meters per second so that it can come to a complete stop at the stop sign?

At a basketball match, a player used his head to (unintentionally) deflect a ball straight up, and 0.5 seconds later, it came back down and struck the player on the head a second time.
