If the coefficient of kinetic friction between tires and dry pavement is 0.90, what is the shortest distance in which you can stop an automobile by locking the brakes when traveling at 22.9m/s ? On wet pavement, the coefficient of kinetic friction may be only 0.25. How fast should you drive on wet pavement in order to be able to stop in the same distance as in part A? (Note: Locking the brakes is notthe safest way to stop.) If...

The coefficient of friction (static and kinetic) between an object and a surface can be measured by putting the object on an adjustable inclined plane. (a) Draw a free-body diagram for the object, assuming static friction holds it in place on the incline. (b) Find an equation that can be used to solve for µs, in terms of the angle θmax which is the largest angle that the object can sit without sliding. (Hint: You can reduce the problem to...

we examined the concept of friction and how it affects everything we do. Air resistance is an important type of friction that you don’t want to forget about as you prepare your post. Consider what the world would be like without friction. For example, in a world without friction, the pitcher in a baseball game can still pitch the ball because he can push off the pitching rubber. The pitching rubber is the rubber slab atop the pitching mound that...

What is the difference between static and kinetic friction. Define both, write their SI unit and dimension. Write down the mathematical statement (formula) that allows us to calculate the force of friction. Explain each term with its unit. Let’s say you’re dragging a 50 kg rubber box on wetconcrete. How do you calculate the force of friction on this box?

A 1830-kg car experiences a combined force of air resistance and friction that has the same magnitude whether the car goes up or down a hill at 34.5 m/s. Going up a hill, the car's engine needs to produce 74.7 hp more power to sustain the constant velocity than it does going down the same hill. At what angle is the hill inclined above the horizontal?

When a car corners at speed one is relying on the friction between the tyres and the road to counter the centrifugal force tending to throw the car outwards. One way to reduce the dependence on friction is to ‘bank’ the corner. For a car travelling with a speed v entering a corner of radius r, show that the angle of the bank, θ, (measured from the horizontal) should satisfy tanθ = v2/(gr) if there is to be no reliance...
