A car travels around a curve with constant speed. The correct statement from the following is the car has an acceleration directed inward toward the center of the curve. the velocity of the car is constant. the car has an acceleration direction outward from the center of the curve. the car has zero acceleration. the car has an acceleration directed in the instantaneous direction of the velocity vector. A ball is whirled on the end of a...

A car travels at constant speed around a corner. The cars speed is 35 m/s and the radius of the circle is 0.25 km. The coefficient of static friction between the tires and the road is 0.7. What is the frictional force needed for the car to make the turn? What is the maximum force the static friction can produce? Does the car stay on the road? The car is in motion so why is the static friction important?

P6 A car travels around a circular track at constant speed, as shown. It is observed that the car takes 15.71 seconds to go from point A to point B along the track (exactly a quarter circle). An accelerometer mounted on the car shows that its acceleration has a constant magnitude of 7.0 m/s2. Please answer each of the following questions. For answers that require vectors, refer to the instant shown in the figure. a) What is the radius of...
