Ⓒ Macmillan Learning An engineer wants to design an oval racetrack such that 3.20 × 10³ lb racecars can round the exactly 1000 ft radius turns at 96 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 96 mi/h without the aid of friction. 0 = 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. What additional radial force is necessary to prevent a race car from drifting on the curve at 175 mi/h? radial force: N

In a charming 19th-century hotel, an old-style elevator is connected to a counterweight by a cable that passes over a rotating disk 2.00 m in diameter (Figure 1). The elevator is raised and lowered by turning the disk, and the cable does not slip on the rim of the disk but turns with it. Part A At how many rpm must the disk turn to raise the elevator at 35.0 cm/s? Express your answer in revolutions per minute. Nνα ΑΣφ W = rpm Part B Figure 1 of 1 To start the elevator moving, it must be accelerated at g. What must be the angular acceleration of the disk, in rad/s?

One of the hazards of prolonged weightlessness on long space missions is bone and muscle loss. To combat this problem, NASA is studying a human-powered centrifuge. In this device, one astronaut pedals a suspended, bicycle-like contraption, while a second astronaut rides standing up in a similarly suspended platform. Part A If the standing astronaut moves with a speed of 3.1 m/s at a distance of 3.2 m from the center of the device, what is the astronaut's centripetal acceleration? Give your answer as a multiple of g, the acceleration due to gravity on the surface of the Earth. Express your answer to two significant figures. να ΑΣφ. ? Submit Request Answer

You've taken your neighbor's young child to the carnival to ride the rides. She wants to ride The Rocket. Eight rocket-shaped cars hang by chains from the outside edge of a large steel disk. A vertical axle through the center of the ride turns the disk, causing the cars to revolve in a circle. You've just finished taking physics, so you decide to figure out the speed of the cars while you wait. You estimate that the disk is 6 m in diameter and the chains are 6 m long. The ride takes 10 s to reach full speed, then the cars swing out until the chains are 30∘ from vertical. What is the car's speed?
