KILCHER HOMESTEAD LIVING MUSEUM. 1  In the early 1940âs Yule Kilcher and his bride Ruth came to Alaska from Switzerland to start a new life in Homer, on the shores of Kachemak Bay. 2  Our family lived the subsistence lifestyle, gathering wild greens, hunting moose and catching salmon for food and growing a large garden.
If the acceleration is negative and the velocity is also negative, the speed of the object increases.Deceleration: It means a reduction in speed or a slowing down. Some confusion is there between deceleration and negative acceleration. Negative acceleration can increase the speed of an object.
Solution. a. The particle has positive acceleration when velocity is increasing. On the intervals (0, 1 s) and (6 s, 7 s), velocity is increasing--slope is positive--and so acceleration is positive.b. Acceleration is the slope of the v-t graph.The graph has zero slope whenever the graph is horizontal; that is, whenever the velocity is constant. This happens in the intervals (1 s, 2 s), 5 s, 6 s) and (7 s, 8 s).. Acceleration is the slope of the v-t graph. The graph has zero slope whenever the graph is horizontal; that is, whenever the velocity is constant. This happens in the intervals (1 s, 2 s), 5 s, 6 s) and (7 s, 8 s).
