- A banked roadway of radius 200m is designed for traffic moving at a maximum speed of 18m/s. Ignoring the friction, the angle at which the roadway is banked is closest to. 13 degrees 9 degrees 18 degrees 7 degreesA curved road with radius 80m is perfectly banked with an angle of 20º. The designed speed of the road is A) 16.89 m/s B) 285.35 m/s C) 29.12 m/s D) 5.4 m/s B O A ос DIf centripetal force is directed toward the center of curvature, why do you feel as if you are “thrown” away from the center as a car goes around a curve? Explain.
- 4) À car travels around a curve banked at 10° to the horizontal. The radius of the curve is 90 m and the car is travelling at 61.2 km/h. Determine μs. 5) An Amazon package (2 kg) starts from rest, then begins to slide down a 4 m tall ramp that is inclined at 30°. The package then travels 12 m along a horizontal surface where it pushes into a spring (k = 3000 N/m). The package compresses the spring a distance x before coming momentarily to rest. Then the package is pushed in the opposite direction by the spring. The coefficient of friction between the ramp/floor and the package is 0.21. Calculate x and determine if the package will stop before it gets back to the ramp or if it will begin to slide up the ramp. h 6) A roller blader (84 kg) is travelling at 19 m/s [E]. A 21.2 kg child is riding a 7.8 kg bike at a speed of 6 m/s [W]. The roller blader and the cycling child collide in what can be assumed to be an elastic collision. What are the final velocities of the roller blader and the…Question: A) A car is driving too fast on a flat non-banked curve. The car cannot stay on the road. What path will the car take as it leaves the road? See Image. B) The driver wants to go faster around the same curve mentioned above and not run off the road. He adds sandbags to his car to make it weigh more so that the friction force between the tires and the road will be increased. Will this work? Explain your answer.
