1.How large must the coefficient of static friction be between the tires and the road if a car is to round a level curve of radius 85 m at a speed of 85 km/h ? 2.Calculate the period of a satellite orbiting the Moon, 170 km above the Moon's surface. Ignore effects of the Earth. The radius of the Moon is 1740 km.

a 1750kg car is parked at the top of a hill with an incline of 12 degrees. Its brakes fail and the car starts rolling down the hill. a) how long will it take for the car to travel 200m and reach the bottom of the hill? (the coefficient of rolling friction between the tires and the road is 0.10) b) what will be its velocity at the bottom?

(2.) A car goes over a hill with a constant speed. Ignoring friction or air resistance, which of the following figures correctly shows the lengths and types of forces that should be on the car's free-body diagram at point A just as the car is at the top of the hill? In the diagrams, n stands for normal force, w is the car's weight, and F is a centripetal force.

(a) Suppose the coefficient of static friction between the road and the tires on a car is 0.60 and the car has no negative lift (aerodynamics pushing it downwards). What speed will put the car on the verge of slipping as it rounds a level curve of 60 m radius? (b) Considering the same friction coefficient, what is the steepest slope the car could be parked on and not slide?

A car is traveling down a hill that makes an angle of 17° with the horizontal. The driver applies her brakes, and the wheels lock so that the car begins to skid. The coefficient of kinetic friction between the tires and the road is μK = 0.53. (a) Find the acceleration of the car. (Take down the ramp to be the positive direction) (b) How long does the car take to skid to a stop if its initial speed is...
