You want to design an oval racetrack such that 3200 lb racecars can round the turns of radius 1000 ft at 105 mi/h without the aid of friction. You estimate that when elements like downforce and grip in the tires are considered, the cars will round the turns at a maximum of 175 mi/h . Find the banking angle ? necessary for the race cars to navigate these turns at 105 mi/h and without the aid of friction. This banking...

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. 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...
