A 960-kg race car can drive around an unbanked turn at a maximum speed of 45 m/s without slipping. The turn has a radius of 160 m. Air flowing over the car's wing exerts a downward-pointing force (called the downforce) of 13000 N on the car. (a) What is the coefficient of static friction between the track and the car's tires? (b) What would be the maximum speed if no downforce acted on the car?

A 810-kg race car can drive around an unbanked turn at a maximum speed of 40 m/s without slipping. The turn has a radius of 120 m. Air flowing over the car's wing exerts a downward-pointing force (called the downforce) of 9200 N on the car. What is the coefficient of static friction between the track and the car's tires? What would be the maximum speed if no downforce acted on the car?

A 900-kg race car can drive around an unbanked turn at a maximum speed of 42 m/s without slipping. The turn has a radius of 170 m. Air flowing over the car's wing exerts a downward-pointing force (called the downforce) of 10000 N on the car. (a) What is the coefficient of static friction between the track and the car's tires? (b) What would be the maximum speed if no downforce acted on the car?

A car of mass M = 1500 kg traveling at 55.0 km/hour enters a level turn (θ=0), and there is a coefficient of static friction μ between the road and the car's tires. What is μmin, the minimum value of the coefficient of static friction between the tires and the road required to prevent the car from slipping? Assume that the car's speed is still 55.0 km/hour and that the radius of the curve is 65.4 m .

A 1200 kg car is practicing on a flat test track. The car begins moving in a 100 m radius circle at a speed of 20 m/s. Viewed above, it is traveling around the circle clockwise, beginning from the top of the circle. (A) What is the centripetal acceleration of the car? (B) How much force is required for this? (C) What is the coefficient of friction between the tires and the track? Three quarters of the way around the...

A car of mass M = 800 kg traveling at 55.0 km/hour enters a
banked turn covered with ice. The road is banked at an angle ?, and
there is no friction between the road and the car's tires as shown
in(Figure 1) . Use g = 9.80 m/s2 throughout this problem.
Now, suppose that the curve is level (?=0) and that the ice has
melted, so that there is a coefficient of static friction ? between
the road and...
