After they are released, object 1 begins to accelerate upward, and object 2 begins to accelerate downward. (Done on the Gradescope submission, for 4 pts.) Draw and label free-body diagrams for both objects. Your diagrams should be qualitatively correct (i. e. forces of the same magnitude should be represented by equal-length vectors, and forces of larger magnitude should be represented by longer vectors), and forces should be labeled with both subscripts and superscripts. (Done on the Gradescope submission, for 4 pts.) The objects have the same magnitude of acceleration, and are released at the same instant, so their velocities at any instant are equal and opposite (i. e. vy,1 = - vy,2). Is the magnitude of the drag force on object 1 greater than, less than, or equal to the magnitude of the drag force on object 2?
If there is not enough information to determine, state so explicitly. Explain your reasoning. (Done on Blackboard, entered below for 3 pts. Explanation should be done on the Gradescope submission for 3 pts.)
When object 2 reaches terminal velocity, the magnitude of the drag force is Fdrag = 60.5 N. The mass of object 2 is m = 16 kg, and the density of water is 1000 kg/m3.
What is the volume of object 2, in units of m3?
Enter your answer to three decimal places.
