The coefficient of kinetic friction between a rubber tire and a dry concrete road is 0.700. What is the distance in which a car will skid to a stop on such a road if its brakes are locked when it is moving at 85 kph?
A wooden crate is at rest on a level stone floor. A. What is the minimum horizontal force needed to start the crate moving? B. What is minimum horizontal force needed to keep the crate in motion at constant speed. C. what will happen if a horizontal force of 500 N is applied to the crate? µs = 0.5 µk = 0.4
A rope whose working strength is 2,000 N is used to tow a 1,000 kg car up a 10 ° incline. Find the maximum acceleration that can be given to the car. The coefficient of friction (µk) between the road and tires is approximately 0.6.
