picture.
A 2,500 kg truck travels at 72.0 km/h and rounds an unbanked curve of radius 80.0 m. The coefficient of static friction between the tires and the road is 0.700, b. Draw a free-body diagram and show all forces on the truck. Determine the force of friction required to keep the truck in the same lane? What is the maximum speed (in km/h) at which the truck can negotiate the cur safely without going off track? c.

You are driving a truck of mass 1800 kg around a curve of radius 55 m. The speedometer reads 13 m/s. The coefficient of static friction between the tires and the road is 0.88. What is the magnitude of the friction force?
2. A car of 1200 kg mass enters an unbanked, curved roadbed of radius 70 m. The coefficient of static friction between the tires and the roadbed is 0.50 A) If the car is traveling at 10 m/s, what is its centripetal acceleration? B) What is the centripetal force on the car? C) What is the frictional force on the tires? D) What is the maximum speed with which the car can take the turn?
A particular unbanked turn in the road is shaped like a circle with a radius of 30 meters. A car with a mass of 1500 kg can safely go around this turn at a maximum speed of 17 m/s. What is the coefficient of static friction between the car's tires and the road?
A 960-kg race car can drive around an unbanked turn at a maximum speed of 45 m/s without slipping. The turn has a radius of 160 m. Air flowing over the car's wing exerts a downward-pointing force (called the downforce) of 13000 N on the car. (a) What is the coefficient of static friction between the track and the car's tires? (b) What would be the maximum speed if no downforce acted on the car?
A 810-kg race car can drive around an unbanked turn at a maximum speed of 40 m/s without slipping. The turn has a radius of 120 m. Air flowing over the car's wing exerts a downward-pointing force (called the downforce) of 9200 N on the car. What is the coefficient of static friction between the track and the car's tires? What would be the maximum speed if no downforce acted on the car?
A 860-kg race car can drive around an unbanked turn at a maximum speed of 44 m/s without slipping. The turn has a radius of 140 m. Air flowing over the car's wing exerts a downward-pointing force (called the downforce) of 11000 N on the car. (a) What is the coefficient of static friction between the track and the car's tires? (b) What would be the maximum speed if no downforce acted on the car?
A 900-kg race car can drive around an unbanked turn at a maximum speed of 42 m/s without slipping. The turn has a radius of 170 m. Air flowing over the car's wing exerts a downward-pointing force (called the downforce) of 10000 N on the car. (a) What is the coefficient of static friction between the track and the car's tires? (b) What would be the maximum speed if no downforce acted on the car?
A 780-kg race car can drive around an unbanked turn at a maximum speed of 42 m/s without slipping. The turn has a radius of 190 m. Air flowing over the car's wing exerts a downward-pointing force (called the downforce) of 11000 N on the car. (a) What is the coefficient of static friction between the track and the car's tires? (b) What would be the maximum speed if no downforce acted on the car?
