QUESTIONS The coefficient of friction between tires and road of an automobile is about 1.30. Let...
(a) Suppose the coefficient of static friction between the road and the tires on a car is 0.60 and the car has no negative lift (aerodynamics pushing it downwards). What speed will put the car on the verge of slipping as it rounds a level curve of 60 m radius? (b) Considering the same friction coefficient, what is the steepest slope the car could be parked on and not slide?
Suppose that the coefficient of friction between a car's tires and the road is 0.600 when the road is dry and 0.350 when the road is wet. If on a certain curve the maximum speed the car can go without slipping is 42.0 m/s when the road is dry, what is the maximum speed the car can go on the same curve without slipping when the road is wet?
You are designing a circular unbanked freeway ramp with a radius of 100. m, the coefficient of static friction between the tires and asphalt is 0.800 dry and 0.400 wet. Find the maximum speed that a car can travel through the ramp during when the road is dry and wet in mph (miles per hour). Vmax, dry = Vmax, wet =
Suppose the coefficient of static friction between the road and the tires on a car is 0.60 and the car has no negative lift. What speed will put the car on the verge of sliding as it rounds a level curve of 31.6 m radius?
Suppose that the coefficient of friction between a car's tires and the road is 0.300 when the road is wet. If the car is going at 70.0 mph on a wet road and applies the maximum braking that does not result in a skid, what distance will it take for the car to stop? (Note: 1 mile = 1.609 km).
Suppose the coefficient of static friction between the road and the tires on a car is 0.814 and the car has no negative lift. What speed will put the car on the verge of sliding as it rounds a level curve of 25.4 m radius? Number Units
An automobile is travelling at 45 m/s on a horizontal road. If the coefficient of static friction between the tires and the road is 0.12, find the minimum stopping distance of the car.
How large must the coefficient of static friction be between the tires and the road if a car is to round a level curve of radius 125m at a speed of 112km/h ? NEED ANSWER
How large must the coefficient of static friction be between the tires and the road if a car is to round a level curve of radius 93 mm at a speed of 94 km/h?
1.How large must the coefficient of static friction be between the tires and the road if a car is to round a level curve of radius 85 m at a speed of 85 km/h ? 2.Calculate the period of a satellite orbiting the Moon, 170 km above the Moon's surface. Ignore effects of the Earth. The radius of the Moon is 1740 km.
