- The graph to the right shows the speed of a truck as it moves along a straight, level road. Which of the following describe a method to determine the distance d the truck travels during the 10 s time interval shown? Select two answers. a Multiply the average speed of 18 m/s by the 10 s travel time. b Calculate the area under the line in the graph. c Multiply half the initial speed of 30 m/s by the 10 s travel time. d Calculate the slope of the line in the graph to determine the acceleration a and then use d = (1 2) 2 at , where t is the travel time.arrow_forwardA car travels along a straight road (in the +x direction). When the car changes speed, it does so uniformly. The position of the car as a function of time is shown in the figure below. Hint: 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, lets you estimate the magnitude of the acceleration. Select the appropriate choice for each statement. Options: {greater than/ less than/ equal to} 1.
