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.

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?

You are advisor to a race car team. Their car is going around an unbanked race track that has a variety of curves in it. The coefficient of friction of the tires is 0.4, meaning that 0.4 mg is the maximum force the tires can exert on the car. They ask you to tell them what is the maximum speed they should drive the car around the sharpest curve which has a nearly circular arc with a radius of curvature...
