Answer #1

acceleration = 3 m/s2

acceleration on a rough road = ug

where u = coefficient of friction

    g = acceleration due to gravity

3 = u*9.8

u = 0.306

so the coefficient of friction required = 0.306

    A 1500-\rm kg car drives at 30 \rm m/s around a flat circular track 300 \rm m in diameter. What are the magnitude and direction of the net force on the car? 9000N Since the net force is equivalent to the force of static friction, your answer to Part D is the magnitude f_s. Based on this value, what is the minimum coefficient mu_s of static friction between the road and the car?

    A 700 kg car is coasting along a level road, slowing down at an acceleration of 7.11 m/s^2 until coming to a stop. What is the minimum coefficient of friction between tires and roadway if this is to be possible? Assume the wheels are not locked, in which case we are dealing with static friction -- there's no sliding.
