A car of mass M = 1500 kg traveling at 65.0 km/hour enters a banked turn covered with ice. The road is banked at an angle 0, and there is no friction between the road and the car's tires as shown in ( Figure 1). Use g = 9.80 m/s² throughout this problem. Figure 1 of 1 Part A What is the radius r of the turn if 0 = 20.0° (assuming the car continues in uniform circular motion around the turn)?

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

a The diagram above shows a yellow car going around a curve in a road (the broad gray line with a white dashed line) as seen from above. In the diagram, the car is moving to the right and slightly upward (notice the headlights are to the right and the tail lights are to the left). At its position shown in the diagram, the road has a radius of curvature r of 43 meters. At the time shown in the diagram, the car is speeding up at a rate of 2.2 m/s?. Also at this time, the total acceleration of the car (shown by a green arrow in the diagram) has a magnitude of 4.2 m/s?. Calculate the speed of the car, in units of meters per second, and this time. .-----
