Question

Ranking Task: Newton's Second Law Shown below are the results of an experiment on six different objects. Each object has varying horizontal forces applied to it on a frictionless table. The corresponding acceleration for each force was measured. A graph of force vs. acceleration was plotted for each object. All graphs use the same scale for the respective axes. Rank the objects according to their mass from least to greatest. Least 1_____ 2_____ 3_____ 4_____ 5_____ 6_____ Greatest Explain the reasoning for your ranking. The acceleration vs. time graph for a robotic arm of mass 50 kg is seen below. What is the net force on the arm that is necessary in order to cause the acceleration between 1 and 2 (as labeled on the graph)? What is the net force on the arm that is necessary in order to cause the acceleration between 3 and 4 (as labeled on the graph)? What is the net force on the arm that is necessary in order to cause the acceleration between 5 and 6 (as labeled on the gr

Explanation / Answer

1)E 2)D 3)B 4) A 5)C 6)F

7)a)50*4.5=225N

b)zero becaus acceleration is zero

c)net force is 50*4.5=225N but in opposite direction
