. Which of the following best explains how air resistance affects the results of the
experiment?
E. With air resistance, TE=TT, because although the sphere slows down, it also
will travel a shorter distance.
Students set up an experiment by attaching an ideal vertical spring to a support and
hanging a block of known mass from the spring. The students pull the block down
and release it from rest. The students then measure the period of the block's
oscillation. This procedure is repeated for several trials using the same spring but
with blocks of different known masses. The students are instructed to create a
linear graph using the mass m of each block and the period T
of the block's motion. The slope of the graph will be used to calculate the force
constant k
of the spring. Which of the following best indicates how the students should create
their linear graph and how k
can be calculated from the slope of the graph?
B. Graph T2 on the vertical axis and m on the horizontal axis; set k=4π^2/slope
. Which variables should be plotted on the horizontal and vertical axes to yield a
linear graph?
C. Vertical: v; Horizontal: y
Block 1 with a mass of 0.18kg is suspended from an ideal spring above a motion
detector, as shown in the figure. The block is pulled down, released from rest, and
allowed to oscillate. The graph of the position x as a function of time t generated
by the motion detector is shown.
Block 1 is then removed from the spring and replaced with a block 2 of unknown
mass. The second block is then pulled down, released from rest, and allowed to
oscillate. The new position as a function of time graph generated by the motion
detector is shown.
