Consider an object in uniform circular motion (constant speed along a circular path).  Which of the following statements is correct? a. The object has no acceleration. b. The centripetal force on the object balances the centrifugal force on the object c. The net force on the object is directed away from the center of the circle. d. The net force on the object is directed toward the center of the circle. e. Both (a) and (b) are correct.

14 A 1 kg ball is tied to the end of a rope and spun around in a vertical circle. The ball is slowly accelerated, spinning faster and faster, until the rope breaks. At what point in the circular motion would you expect the rope to break? Group of answer choices bottom top left right

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?

6. A car is driving around a corner with a radius of curvature of 50.0m. If the coefficient of friction between the tires and the road is 0.460, what is the maximum speed the car can travel to make the corner? What would happen if the car travelled faster than this speed?

46. Please help answer this question thank you so much!:))

Question 8 A car is travelling into an unbanked turn with radius of 11.0 m. The coefficient friction is 1.4. What is the maximum speed the car can travel and still be able to maintain a circular path? Answer in m/s to one decimal place. Your Answer: Answer Question 9 A ball on the end of a string is swung in a vertical circle. The length of the string is 0.4 m. What is the minimum speed required to maintain the circular motion? Answer in m/s to one decimal place. Your Answer: Answer units

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. [Show all work, including the equation and substitution with units. ]

2. A car of mass 1.1 x 103 kg travels around a frictionless, banked curve of radius 85 m. The banking is at an angle of 190 to the horizontal. a) Draw a free body diagram for the above scenario. b) What constant speed must the car move at to travel safely around the curve? c) How does the required speed for a more massive vehicle, such as a truck, compare with the speed required for this car?
