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 NASCAR racecar rounds one end of the Martinsville Speedway. This end of the track is a turn with radius approximately 57.0 m. If we approximate the track to be completely flat and the racecar is traveling at a constant 26.5 m / s (about 59 mph) around the turn, what is the racecar\'s centripetal (radial) acceleration? What is the force responsible for the centripetal acceleration in this case? friction, normal, gravity, or weight? To keep from skidding into the...
