What is the coefficient of static friction between the road and the car tyres?
Jones and Childers report coefficients of friction of about 0.7 for dry roads and 0.4 for wet roads. The tread design represents an “all weather” compromise. If you were an Indianapolis race driver, you would use “slick” racing tires with no tread.
What would be the maximum speed of a car on a road turn of radius 10 m if the coefficient of friction between the tyres and the road is 0.2 g 9.8 m/s 2 * 1?
v=√μgR=√0.4×9.8×30=√117.6=10.84 . Thus, the maximum velocity that can be attained by the vehicle while making the turn is 10.84 m/s.
What will be the maximum speed of a car on a road turns of radius 30 m?
The maximum speed of a car on a road–turn of radius 30 m, if the coefficient of friction between the tyres and the road is 0.4, will be. 6.84 m/sec.
What is the minimum coefficient of friction that must exist between the truck tires and the road?
The minimum friction coefficient required is 0.4 .
What coefficient of friction is needed to keep the car on the road?
Of course, any coefficient of friction greater than 0.141 will keep the car from slipping; this is the minimum value for . Notice that the force of friction is perpendicular to the velocity. But it still is in the direction necessary to oppose the motion that would occur without friction.
What will be the maximum speed of a car?
Record-breaking production vehicles

|---|---|---|
| 2005 | Bugatti Veyron EB 16.4 | 408.47 km/h (253.81 mph) |
| 2007 | SSC Ultimate Aero | 412.22 km/h (256.14 mph) |
| 2010 | Bugatti Veyron 16.4 Super Sport | 431.072 km/h (267.856 mph) |
| 2017 | Koenigsegg Agera RS | 447.19 km/h (277.87 mph) |
What will be the maximum speed of car?
In April 2018, the Union Ministry of Road Transport and Highways fixed the maximum speed limit on expressways at 120 km/h, for national highways at 100 km/h, and for urban roads at 70 km/h for M1 category of vehicles. The M1 category includes most passenger vehicles that have less than 8 seats.
What is the maximum speed of a car on a road of radius 30 m if the coefficient of friction between the road is 0.4 Take g 9.8 m S 2?
What will be maximum speed of a car on a curved road of radius 30 m , If the coefficient of friction between the tyres and the road is 0.4? (g=9.8 m//s^(2)) =√105.6=10.84m/s.
