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 time is shown in the figure below. When the car changes speed it does so uniformly. Select the appropriate choice for each statement 2000 800 600 400 200 20 40 60 80 Time (s) Less tha Greater than Equal to Greater than Equal to At 79 sec, the speed is as high as it gets The acceleration magnitude at 37 sec is.. the acceleration magnitude at 15 sec The x-acceleration is.. zero at 26 sec The speed at 10 sec is. the speed at 79 sec The speed is.. zero at 20 sec. Less tha The x-acceleration is.... zero at 15 sec By extrapolating the straight sections of the graph, you can estimate the time during which the speed is changing. This, with the change in speed, shõuld let you estimate the magnitude of the acceleration Enviar Respuesta Incorrecto. Tries 4/10 Intentos Anteriores Using the graph above, calculate the average speed of the car for the period from 0 to 20.0 s
