Review of concepts After reviewing the text, answer the following questions

Question 1 The graphs in the figure below show acceleration and velocity of an object as it experiences three different accelerations. Figure (a) shows a (t ) , and Figure (b) shows v(t ) . For each of the three cases determine whether the object is speeding up, slowing down, or moving with a steady speed. v
