***BASED on the INSTRUCTIONS ***see 21 graphs labeled with numbers:
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 (10) (13) (16) (19) (14) (17) (12) (15) (18) (21) PROBLEM #1 Motion Diagram At the beginning, the object is at rest at the origin. Then, the object is moving to the right at a(n) constant positive acceleration. r's answer now shown above. You are correct. What is the number of the graph that best represents the position x? What is the number of the graph that best represents the velocity v? Tries 0/3 What is the number of the graph that best represents the acceleration a? Ane Tries 0/3Explanation / Answer
1]
a] It is given that the acceleration is varying as x increases.
Since x2 > x1 , v2 > v1
and so the graph which represents x-t graph of the motion is (14) since the displacement is zero at t = 0 and the increasing trend is quadratic.
b] v = dx/dt
Therefore, v-t graph will be linear (since a is given to be constant)
the graph which fits this motion is (5).
c] Acceleration remains constant in time and is positive in value. It is thus given by (1).
