**12. The positions of objects A and B are graphed at right. Answer the following questions and explain. a) Is the acceleration of object A positive, negative, or zero at t = 2 s? b) At t = 2 s, is object B speeding up, slowing down, or mov- ing with constant speed? c) Is the acceleration of object B positive, negative, or zero at t = 2 s?

Please answer the question to the right by using the info on the left. Need to find the maximum height first. Please circle both the maximum height answer and time in the air answer

Help Please. Thank you very much.

Figure below is a velocity-versus-time graph for a moving object. The object starts at position x = 0. What is the acceleration at t= 1.0 s, in m/s2? Your answer needs to have 3 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit is needed in your answer, it is already given in the question statement. time in seconds

* e In figure below, the area under the velocity-versus-time graph and between the vertical axis and time t (vertical dashed line) represents the displacement. As shown, this area consists of a rectangle and a triangle. Slope = a. at (a) Compute their areas. (Use any variable or symbol stated above as necessary.) Arectangle Atriangle (b) Explain how the sum of the two areas compares with the expression on the righthand side of x, = x. + vt +

Instructions:You will be given one description of motion (words, motion diagram, graph of position x, velocity v, or acceleration a) and asked to complete the other descriptions of motion. For the paragraph response, select the choices from the drop-down menus that best complete the description of motion. For the position, velocity, and acceleration graphs, you will need to enter the number of the graph from the illustrated chart that best depicts the correct curve. Problem #4  a. At the beginning, the object is located {to the left of/ to the right of/ at} the origin. The object then moves to the {left/ right} with {increasing/ decreasing/ constant} speed and {increasing/ decreasing/ constant} {positive/ negative} acceleration. b. What is the number of the graph that best represents the velocity v? c. What is the number of the graph that best represents the acceleration a?
