A car is rounding an unbanked circular turn with a speed of v = 35 m/s....
A car is safely negotiating an unbanked circular turn at a speed of 29 m/s. The road is dry, and the maximum static frictional force acts on the tires. Suddenly a long wet patch in the road decreases the maximum static frictional force to one-sixth of its dry-road value. If the car is to continue safely around the curve, to what speed must the driver slow the car? m/s
a) A block of wood resting on a ramp. b) A car rounding a turn with a constant radius and a constant speed. c) A car driving down a road with a constant velocity d) A baseball player sliding into home plate. 2. Consider the following two situations. A car is traveling around a turn of radius R with a constant velocity. The same car now navigates a turn with twice the radius and twice the velocity. The centripetal acceleration...
Question 1 (uniform circular motion) A 1500 kg car is taking a left turn at a constant speed of 10 m/s. The radius of the turn is 12 meters. a. What is the centripetal acceleration on the car? b. How much force is require to hold the car in that turn? c. What force(s) is responsible for the centripetal force on the car?
1. A test car moves at a constant speed of 10 m/s around a circular road of radius 50 m. Find the car's centripetal, tangential and total acceleration.
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?
