When you take your 1200-kg car out for a spin, you go around a comer of radius 50 m with a speed of 20 m/s. The coefficient of static friction between the car and the road is 0.88. Assuming your car doesn't skid, what is the force exerted on it by static friction? Express your answer using two significant figures.
A remote control car of mass 2,000 grams turns about a corner on a racetrack. While making the turn, it experiences a centripetal force of 0.9 N. If the toy car is traveling around the corner at a speed of 3.0 m/s, (a) what is the centripetal acceleration of the car? (b) What is the radius that the car turns about?
A car travels at constant speed around a corner. The cars speed is 35 m/s and the radius of the circle is 0.25 km. The coefficient of static friction between the tires and the road is 0.7. What is the frictional force needed for the car to make the turn? What is the maximum force the static friction can produce? Does the car stay on the road? The car is in motion so why is the static friction important?
1) A car with mass m = 1000 kg is traveling around a circular curve of radius r = 990 m when it begins to rain. The coefficients of static friction between the road and tires is μd = 0.66 when dry and μw = 0.26 when wet. a) Write an expression for the maximum magnitude of the force of static friction Ff acting on the car if μs is the coefficient of friction. b) What is the maximum tangential...
A race car is traveling at a constant speed of 102 m/s around a circular track with a radius of 3250 m. How long does it take the race car to go around the track once? Express your answer in seconds.
Answer both parts. (a) A car drives around two horizontal circular bends, Around the first, with a radius of 55 meter, the car has a max speed of 24 m s-1 before it starts to skid. The second bend has a radius of 110 meter. How fast can the car go around the second bend without skidding? (b) An object starts at rest and moves around a 25 meter radius circle with constant tangential acceleration ay = 0.3 ms 2....
1. A car travels at constant speed around a horizontal circular corner of radius 5 m. n (a) Given that the car just starts to skid if its speed is 12 km/h, find the frictional force acting on the car. (b) Assuming the same frictional force is acting, calculate the car's smallest possible turning radius if the speed is 30 km/h. (c) Calculate the turning radius for the car travelling at 12 km/h in wet conditions where the frictional force...
Suppose a car is driving down the road at a speed of 15m/s^2. The car hits the brakes, inducing an acceleration of -2.5m/s^2. How long would it take, in seconds for the car go fully stop.
A pizza delivery car is travelling around a corner of radius 50m at 60km/h. The road is level, however at this speed the car tilts over on its suspension at an angle of 5º. The 2kg sign on their roof is held on by magnets that provide an attractive force of 50N 50m [PIZA Neglecting wind resistance; (a) Draw a free body diagram of the 'Pizza' sign showing all forces that act. [2 marks] (b) Calculate the magnitude of the...
A car travels at a constant speed around a circular track whose radius is 2.65 km. The car goes once around the track in 341 s. What is the magnitude of the centripetal acceleration of the car?
