Work Step by Step
To go from acceleration to velocity on graphs, you need to look at the values on the y-axis of the acceleration graphs. These values correspond to the slopes on the velocity graphs.
Because the acceleration is initially zero, the initial slope on the velocity graph must be zero. Then, because the acceleration is negative, the slope must be negative on the velocity graph. This rules out graph d since it continues to have a slope of zero.
