A test driver attempts to drive a car with constant speed around a horizontal circular track of radius R = 200 m. The coefficient of static friction of the tires perpendicular to the direction in which the car is traveling is µs = 0.05. Give the shortest possible lap time the driver can achieve.
Spy Agent 001 is chasing the bad guys. Suddenly, 001 needs to turn his car (m = 1000 kg) around, and completes a turn in the shape of a semi-circle (radius = 60 m) travelling at a constant speed of 27 m/s. a) If the static coefficient of friction between the tires and the pavement is 0.55, find the maximum force of friction before slipping occurs. b) Will the car be able to complete the turn without sliding? c) To...
Calculate the maximum acceleration of a car that is heading up a 6∘ slope (one that makes an angle of 6∘ with the horizontal) under the following road conditions. Assume that only half the weight of the car is supported by the two drive wheels and that the coefficient of static friction is involvedthat is, the tires are not allowed to slip during the acceleration. (Ignore rolling). a) On dry concrete: b) On wet concrete: c) On ice, assuming that...
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?
