Question

Traveling Car Puntos:2 A car travels a certain distance along a straight road (in the +x direction). The distance the car travels as a function of each statement. time is shown in the figure below. When the car changes speed it does so uniformly. Select the appropriate choice for 1000 600 400 200 20 40 60 80 Time (s) Less han The acceleration magnitude at 37 sec isthe acceleration magnitude at 15 sec. The x-acceleration is zero at 58 sec. At 50 sec, the speed is as high as it gets. The speed is zero at 20 sec. The speed at 67 sec is the speed at 50 sec.

Explanation / Answer

1. equal (because v is constant)

2.  less than (at 15s curvature is less than vurvature at 37s)

3. less than

4. True ( slope is maximum )

5.   less than

6. less than

Average speed

Vav = distance/time = 400/40 = 10 m/s
