Packet #1
D.) Practice: Open-response Question #2
BE SURE TO ANSWER AND LABEL ALL PARTS OF THE QUESTION.
Show all your work (diagrams, tables, or computations)
If you do the work in your head, explain in writing how you did the work.
The figure below is a graph of net force vs. the acceleration of an object.
a. Use the graph to determine the mass of the object. Show your calculations and include units in
your answer.
b. What acceleration will the object have if the net force is 50 N and the trend shown by the
graph continues? Show your calculations and include units in your answer.
c. On the grid in your Student Answer Booklet, draw a graph of force vs. acceleration if the mass
of the object is halved and the object is subjected to the same net forces. Label the axes on your
graph and be sure to include units. Label this graph “c.”
d. On the same axes that you used in part (c), draw a graph of force vs. acceleration if the mass
of the object is doubled and the object is subjected to the same net forces. Label this graph “d.”

m=10/5=2kg
b.) a=F/m
a=50N/2kg
Mass is
halved.
