An 800. kg racecar travels on a flat circular track of radius 250 m. Assuming the car moves with a constant speed of 45.0 m/s, find (a) its angular speed, (b) the magnitude and direction of its acceleration, and (c) the minimum static coefficient of friction, between the tires and the road, that keeps the car from slipping.

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 1500-kg car drives at 30 m/s around a flat circular track 300 m in diameter. What are the magnitude and direction of the net force on the car? Sort the following quantities as known, to find, or unneeded. Let m and v be the mass and speed of the car, respectively; μs is the coefficient of static friction, r is the radius of the circular path, n is the magnitude of the normal force acting on the car, and...

A car drives around a flat 119 m radius circular track at 20 m/s. Assume that this speed is the maximum speed that the car can have without out "skidding out" of the curve.The car moves into the next curve. The radius of this new curve is twice as great as the previous. Assume the coefficient of static friction has not changed. Calculate the car's maximum speed in this curve. m/s

A car travels around flat, un-banked, circular track with a maximum speed of 20 m/s. If the coefficient of friction between the car tires and the track is 1.0, and the normal force between the car and the track is due to the weight of the car (no aerodynamic effects), what is the radius of the track?
