- An engineer is trying to determine the speed at which a car can travel around a curved race track without using any friction, Assume the car does not move up or down the incline and completes a horizontal circle. Complete all calculations under these circumstances. Hint: Use the variable m for the mass of the car, it will cancel! number of forces in plane: centripetal force: 340m Are all forces balanced? 160 What is the magnitude of the centripetal acceleration? unit At what speed does the car need to travel? unit finalize check answers cannot be determined (after completing ALL problems) Unit 10: circular motion, challenge Desmos Scientific Online Calculator hp esc HAAR @ #3 2$ & 96Which statement below is incorrect with regard to curved roads? Racetracks have banked turns so cars do not have to slow down too much when navigating them Given several turns of the same radius, made of the same material but at different bank angles, the one which could be navigated at the highest speed would the one with the steepest bank. 4 wheel drive allows one to drive faster around turns in the winter If made of the same material and under the same conditions, a banked curve can always be navigated at a higher speed than a flat curve of the same radius. A banked turn can be navigated safely even if completely covered in iceA child sitting 1.90 m from the center of a merry-go-round moves with a speed of 2.15 m/s - Calculate the centripetal acceleration of the child. - Calculate the net horizontal force exerted on the child. (mass = 34.5 kg)
- 5. When you whirl a ball on a cord in a vertical circle, you find a critical speed at the top for which the tension in the cord is zero. This is because the force of gravity on the object itself supplies the necessary centripetal force. How slowly can you swing a 2.5 kg ball like this so that it will just follow a circle with a radius of 1.5 m?If 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.What is the maximum speed with which a 1300 kg car can round a turn of radius 100.0 m if the coefficient of static friction between the tires and the road is 0.70? Does the result depend onthe mass of the car? What is the centripetal acceleration of the car at the maximum speed it can go around the turn? What is the corresponding centripetal force on the car?
- 2) Base your answer to the question on the information below and on your knowledge of physics. A gas-powered model airplane has a mass of 4.50 kilograms. A student exerts a force on a cord to keep the airplane flying around her at a constant speed of 50.0 meters per second in a horizontal, circular path with a radius of 100 meters. Calculate the magnitude of the centripetal force exerted on the airplane to keep it moving in this circular path.
