Make a prediction of vertical velocity versus time (vy vs. t) for a ball in free fall from bouncing vertically on a table. You want to predict the entire motion from right after the first contact with the table (on its way up), to the top of the motion, and back down to the table at the instant before the ball hits the table for the second time (on its way down, but hasn’t hit yet). Graph only predictions for...

3. The following graph is a velocity-position plot that shows the velocity v versus height y of a ball that is tossed directly upward in the vertical direction. (Note: this is a different type of graph compared to the position-time and velocity-time graphs that you have seen in class.) a. What part of the ball's motion does this graph describe? (In other words, does it describe the ball's total overall motion up and down? Only the upward motion? Only the...

a) State without any calculations which object has a greater
displacement over the time interval shown in the graphs? Explain
your answer
b) Calculate the displacement values for the objects A and B at
the time moments of
- 10s
- 30s
- 60s
c) Assuming that at t=0 both objects were located at x= 0, make
graphs of the position versus time for each object, for the entire
interval from 0-60s. ( Don't have to actually do this but...

A rock moving through deep space in the +x direction, at time t = 0 a constant F vector begins to act on it. Select all that apply. For time t > 0, which are possible functions x(t) for the rock's position? For which function F vector directed opposite the rock's initial direction of motion? Select all that apply.
