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.
Find the velocity vector v(t) if the position vector is r(t) = 3ti + 2t 2 j - sin t k . Solution. We just take the derivative v(t) = 3i + 4tj + cos t k . When we think of speed, we think of how fast we are going. Speed should not be negative. In one variable calculus, speed was the absolute value of the velocity.
