A car rounds a curve on a flat road at constant speed. The car and driver have a combined mass of 950 kg and the curve has a radius of 68 m. The coefficient of static friction is 𝜇_𝑠=0.5. What is the maximum speed v with which the car around the curve without skidding?
Car A can travel around a curved section of road without skidding at a maximum constant speed of 10 m/s. When car B travels around the same curve without skidding at its maximum speed, it has twice the centripetal acceleration as car A. The maximum speed at which car B can safely travel around the curve is most nearly
A race car moving with a constant speed of 60 m/s completes one lap around a circular track in 50 s. What is the magnitude of the centripetal acceleration of the race car?
