A car moves at a speed of 36 km hr-1 on a level road. The coefficient of friction between the tyres and the road is 0.8. The car negotiates a curve of radius R. If g = 10 ms-2 , then the car will skid (or slip) while negotiating the curve, if the value of R is ____________. A car moves at a speed of 36 km hr-1 on a level road. The coefficient of friction between the tyres and the road is 0.8. The car negotiates a curve of radius R. If g = 10 ms-2 , then the car will skid (or slip) while negotiating the curve, if the value of R is 12 m. Explanation: The speed with which the car turns is `"v"^2 ge mu"Rg"` `therefore "R" le ((36 xx 10^3)/3600)^2 xx 1/(0.8 xx 10)` ` = 12.5 "m"` `therefore "R" le 12.5 "m"` `therefore "R" = 12 "m"` Concept: Applications of Uniform Circular Motion Is there an error in this question or solution? |
