You are testing out your driving ability in an empty parking lot. You drive at 85 km/hr towards a solid wall.
When you are 62 m away from the wall, you begin to brake. What minimum coefficient of friction between the road and the tires is required so you stop before hitting the wall?

You are driving your car along a flat, curved road; the curve in the road is a segment of a circle with radius 50 meters. (We call this a "radius of curvature"). How fast can the car drive around the curve if the coefficient of static friction between the tires and the road is 1.0 (tires on dry pavement)? What if the coefficient of friction is 0.2 (tires on ice)?

3. You are driving on the freeway at 80 mph, trailing the car in front of you by two seconds. Suddenly, the car in front of you - also traveling at 80 mph brakes to stop; its tires are new, with a friction coefficient of 0.8. Your car, on the other hand, has poor tires with a coefficient of 0.5. Due to distracting music and passengers, you do not...

You are driving at 30m/s and hit your breaks, skidding to a stop. The static coefficient of friction between your tires and the road is μs = 0.7. The mass of your car is 1500 kg. a) What is your initial kinetic energy right before you hit the breaks? b) What is the magnitude of the static friction force acting on the car? c) Does the friction do positive or negative work on the car? Explain your reasoning. d) Use...

020 (part 1 of 3) 10.0 points You are driving at the speed of 34.8 m/s (77.862 mph) when suddenly the car in front of you (previously traveling at the same speed) brakes and begins to slow down with the largest deceleration possible without skid- ding. Considering an average human reaction, you press your brakes 0.576 s later. You also brake and decelerate as rapidly as possible without skidding. Assume that the coefficient of static friction is 0.722 between both...
