A car travels along a straight line at a constant speed of 53.0 mi/h for a distance d and then another distance d in the same direction at another constant speed. The average velocity for the entire trip is 31.0 mi/h what the constant speed with which the car moved during the second distance d? suppose the second distance d were traveled in the opposite direction: you forgot something and had to return home at the same constant speed as...

Problem A car travels at a constant speed of 29.5 mi/h (13.2 m/s) on a level circular turn of radius 46.0 m, as shown in the bird's-eye view in Figure 7.13a. What minimum coefficient of static friction, Aus, between the tires and the roadway will allow the car to make the circular turn without sliding? Strategy In the car's free-body diagram (Fig. 7.13b) the normal direction is vertical and the tangential direction is into the page (step 2). Use Newton's...
