Rank the points in order of increasing acceleration (from most negative to most positive). Practice walking this plotted motion. 8.24) The velocity graph of a 1 g coffee filter released from rest is shown below. Note the break in the time axis. Four distinct intervals are shown on the graph. a) Speed downward increasing from rest, 0 s ≤ t ≤ 0.02 s. b) Speed downward increasing, 0.02 s ≤ t ≤ 0.09 s. c) Speed downward is constant, 0.09 s ≤ t ≤ 4.99 s. d) Landing on the floor, 4.99 s ≤ t ≤ 5.00 s. Draw an acceleration graph for the same time intervals above. You may use the tangent lines drawn on the velocity graph to calculate the average slopes of the velocity curve during the first two intervals. 8.25) Refer to the graphs on the reverse which were made using a motion detector mounted above a basketball that was dropped from a height of 1.5 m above the floor. The position measured and indicated is really the position of the top surface of the ball. The velocity graph was computed by the software as the derivative of the position vs. time graph. Complete the following tasks related to this...
