Q. The graph to the right is a plot of position versus time. For which labeled region is the velocity positive and the acceleration negative?Physics Question Image

Motion in a Straight Line

Solution:

In part (d), slope is positive and decreasing, so velocity is positive and decreasing. If velocity is decreasing, then acceleration is negative.
