A circular-motion addict of mass 81.0 kg rides a Ferris wheel around in a vertical circle of radius 12.0 m at a constant speed of 7.10 m/s. (a) What is the period of the motion? What is the magnitude of the normal force on the addict from the seat when both go through (b) the highest point of the circular path and (c) the lowest point? Unit of Part A is s, Part B and C is N.

A circular-motion addict of mass 85 kg rides a Ferris wheel around in a vertical circle of radius 10 m at a constant speed of 5.7 m/s. (a) What is the period of the motion? (b) What is the magnitude of the normal force on the addict from the seat when both go through the highest point of the circular path? (c) What is it when both go through the lowest point?

The accompanying figure shows a frictionless channel in the shape of a segment of a circle with center at "O". The channel has been anchored to a frictionless horizontal tabletop. You are looking down at the table. Forces exerted by the air are negligible. A ball is shot at high speed into the channel at "p" and exits at "r." Consider the following distinct forces: A downward force of gravity. A force exerted by the channel pointing from q to O. A force in the direction of motion. A force pointing from O to q.     Which of the above forces is (are) acting on the ball when it is within the frictionless channel at position "q"?

A small car with mass 0.600 kg travels at constant speed on the inside of a track that is a vertical circle with radius 5.00 m (Figure 1 Figure B V 5.00 m K 1 of 1 If the normal force exerted by the track on the car when it is at the top of the track (point B) is 6.00 N, what is the normal force on the car when it is at the bottom of the track (point A)?

A 43-kg child riding a Ferris wheel (radius = 13 m) travels in a vertical circle. The wheel completes one revolution every 17 s. What is the magnitude of the force on the child by the seat (i.e. normal force) at the highest point on the circular path?

A circular-motion addict of mass 81.0 kg rides a Ferris wheel around in a vertical circle of radius 14.0 m at a constant speed of 7.10 m/s. (a) What is the period of the motion? What is the magnitude of the normal force on the addict from the seat when both go through (b) the highest point of the circular path and (c) the lowest point?

An engineer wants to design an oval racetrack such that 3.20 × 10³ lb racecars can round the exactly 1000 ft radius turns at 1.00 x 102 mi/h without the aid of friction. She estimates that the cars will round the turns at a maximum of 175 mi/h. Find the banking angle necessary for the race cars to navigate the turns at 1.00 × 10² mi/h without the aid of friction. 0 = What additional radial force F, is necessary to prevent a race car from drifting on the curve at 175 mi/h? This banking and radius are very close to the actual turn data at Daytona International Speedway, where 3.20 × 10³ lb stock cars travel around the turns at about 175 mi/h. 0 Fr= N
