Would
this be correct to this answer and could you explain why or why not
and what would be the answer if so? Thank you!!
Homework Answers
As it is falling freely, so displacement is negative and velocity is increasing but negative so graph b and a are wrong
The correct option is c.
As displacement and velocity both are negative.

" A mass hanging from a vertical spring is somewhat more complicated than a mass attached to a horizontal spring because the gravitational force acts along the direction of motion. Therefore, the restoring force of the oscillations is not provided by the spring force alone, but by the net force resulting from both the spring force and the gravitational force. Ultimately, however, the physical quantities of motion...

Please explain
For each of the velocity vs. time graphs below, sketch possible comesponding position vs. time and acceleration vs. time graphs. To the right of the graph, briefly describe the motion of the object and why the graphs you drew are consistent with the velocity graph. Where is the object at time t 0 in each case? Explain
