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.
