Show all of your work, even though the question may not explicitly remind you to do so. Clearly label any functions, graphs, tables, or other objects that you use. Justifications require that you give mathematical reasons, and that you verify the needed conditions under which relevant theorems, properties, definitions, or tests are applied. Your work will be scored on the correctness and completeness of your methods as well as your answers. Answers without supporting work will usually not receive credit. Unless otherwise specified, answers (numeric or algebraic) need not be simplified. If your answer is given as a decimal approximation, it should be correct to three places after the decimal point. Unless otherwise specified, the domain of a function f is assumed to be the set of all real numbers for which f) is a real number. A particle moves along the l-axis so that its position at time t>O is given by < (t) (a) Show that the velocity of the particle at time t is given by 0 (t) = (240)2. se respond on separate paper, following directions from your teacher. (b) Is the particle moving toward the origin or away from the origin at time t = 2 ? Give a reason for your answer. lease respond on separate paper, following directions from your teacher. (c) The acceleration of the particle is given by a (t). Write an expression for a (t), and find the V (d) what position does the particle approach as(t) approaches infinity
