The speed limit on a particular city street is 45 miles per hour (which is 20 m/s). A driver approaching a stop light slams on their brakes, locking the wheels of their car in place so that they no longer rotate. If the coefficient of friction between the car's tires and the street is 0.9, what is the minimum distance the driver would need to start braking in order to stop before the intersection?

A car is moving on a city street at a speed of 30 km/h. The driver sees a red traffic signal ahead and slams on the brakes, providing an acceleration that has magnitude 6.0 m/s2. The driver's reaction time is 0.50 s. (a) Determine the displacement of the car until it stops. ___m (b) Repeat Part (a) if the initial speed is 60 km/h and the braking acceleration is the same as in Part (a). ___m

Brake or turn? Figure 6-45 depicts an overhead view of
a car's path as the car travels toward a wall. Assume that the
driver begins to brake the car when the distance to the wall is
d = 109 m, and take the car's mass as m = 1430
kg, its initial speed as v0 = 37.0 m/s, and the
coefficient of static friction as μs = 0.530.
Assume that the car's weight is distributed evenly on the four
wheels,...

The city is trying to figure out how long the traffic light should stay yellow at an intersection. The speed limit on the road is 45.0 km/h and the intersection is 23.0 m wide. A car is traveling at the speed limit in the positive direction and can brake with an acceleration of ?5.20 m/s2. (a) If the car is to stop on the white line, before entering the intersection, what is the minimum distance from the line at which...

As a city planner, you receive complaints from local residents about the safety of nearby roads and streets. One complaint concerns a stop sign at the corner of Pine Street and 1st Street. Residents complain that the speed limit in the area (89 km/h) is too high to allow vehicles to stop in time. Under normal conditions this is not a problem, but when fog rolls in visibility can reduce to only 47 meters. Because fog is a common occurrence...
