Under normal driving conditions, car tires can generate a fiction coefficient of approximately 0.7. Antilock braking systems can increase the effective coefficient of friction to as high as 1.0. For car traveling 65 miles an hour, determine the stopping distance for coefficients of friction of 0.7 and 1.0. How much more time do antilock brakes give the driver to respond. Also, why have antilock brakes not produced reductions in crash rates that were anticipated from this calculation?

A red car and a blue car are driving in the same direction on the interstate. The red car is travelling at 25 m/s, while the blue car is travelling at 35 m/s. The driver of the blue car is not paying attention and rear-ends the red car. The red car has a mass of 2,000 kg while the blue car is only 1,000 kg. a. Prior to the collision, what is the value of the center of mass kinetic...

A 1210 kg car is driving on 60 km/h on an inclined plane. The car is located on the top of the plane. The plane is 655 m long and the angle is 4.50 degrees. a) What will the speed of the car be if there is no friction ? b) Now the car is on 85 km/h at the bottom of the inclined plane. How much friction force works on the car its way down ? c) If the...

A mass of 5 kg is placed on a horizontal surface with a coefficient of kinetic friction of 0.4. A force is applied vertically downward to it and another force of 81 Newtons is applied at 14 degrees below the horizontal. As it moves 5 meters in the +x direction it loses 180 Joules of kinetic energy. What is the amount of the force which is applied downward in Newtons?

A person is driving his car on some road and suddenly a police car stops him for speeding, the police-detected radar gun emits a wave whose frequency is 8.0 × 109 ??. 1. How do you think the mechanism by which you know how fast a moving car can go works? 2. Does it depend on the speed of the police car? Does it depend on the speed of the person's car? 3. Does it depend on the two speeds?...
