Report

A physics professor leaves her house and walks along the sidewalk toward campus. After 5 min, she realizes that it is raining and returns home. The distance from her house as a function of time is shown in Figure $2.46 .$ At which of the labeled points is her velocity (a) zero? (b) constant and positive? (c) constant and negative? (d) increasing in magnitude? and (e) decreasing in magnitude?

in this problem, we are going to consider in Stanton years velocity and stood off after its velocity on DH. Starting at velocity is given by the slope of the tangent to the ex forces Big graph or simply the ex over ditty. Now for the first ballot on the graph is horizontal. So this means that eggs this constant with kind this implies the X zero at all times. So from this equation, we can say that velocity and Siegel your point four not for five b ah velocity is constant on positive where the graph is a straight line that positive slope. This means that this should be 0.1 now, from the third part, the velocity ah is constant and negative. This means the graph is a straight line with negative slope. This corresponds to point fight with the fourth part. The slope is positive and increasing at point two on DH slope is positive and decreasing a fine tree
