The Texas Motor Speedway is an oval racing track with curves of radius 229 m that are banked at an angle of 24.0°. The size of the track allows for race cars to achieve speeds in excess of 400 km/h. An unintended consequence of the banked curves and high speeds is that race car drivers experience excessive G forces, especially in the "vertical" direction (with respect to their body position), causing dizziness and loss of consciousness. (a) A daring driver,...

A car with a mass of 2000 kg is moving around a banked curve with a constant speed of 20 m/s (about 44 MPH). The radius of curvature of the curve is 73 m. (a) What is the centripetal acceleration of the car? (b) What is the magnitude of the horizontal component of the normal force that would be required to produce this centripetal acceleration in the absence of any friction?

A race car rounds one end of a speedway. This end of the track is a turn with a radius r of approximately 187 ft. If the track is assumed to be completely flat and the race car is traveling at a constant 67.00 mi/h around the turn, what is the race car's centripetal (radial) acceleration ac? 1) ac= ft/s2 Convert this result to SI units. 2) ac= m/s2 3) What is the force responsible for the centripetal acceleration in...

A race car rounds a curve at 59 m/s. The radius of the curve is 403 m, and the car's mass is 640 kg. (Assume the car's speed remains constant. Take the radially inward direction to be positive. Indicate the direction with the sign of your answer.) (a) What is the car's (centripetal) acceleration? (b) What is it in g's? (enter value to 3 decimal places) (c) What is the centripetal force acting on the car?

a. Calculate the maximum safe speed for a 2 ton car traveling around a curve with a radius of 150 yards given a force of friction of 650 N. Provide your answer in m/s and mph. At the maximum safe speed, what is the centripetal acceleration of the car? Given that the force of friction remains 650N, if the car is traveling at twice the maximum safe speed around a curve with a radius that is twice as large, will...

A section of a high speed test track is circular with a radius
of curvature R = 1700 m.
At what angle of θ should the track be inclined so that a car
traveling at 77.0 m/s (172 mph) would keep moving in a circle if
there is oil on that section of the track, i.e., it would not slip
sideways even with zero friction on that section. (Hint: The car's
vertical acceleration is zero.)
