0 1 This question is about an experiment to determine g by a free-fall method (required
practical activity 3).
Figure 1 shows the apparatus used.
A metal ball is positioned so that the bottom of the ball is level with a fiducial mark on
a vertical wall.
Figure 1
0 1 . 1 Annotate Figure 1 to show how a set square can be used to check that the ball is
positioned correctly.

The ball is released from rest so that it falls vertically through the two light gates. box
When any part of the ball blocks the light in a light gate, the output voltage V from the
gate is 5 V.
When the ball does not block the light in a light gate, V is 0 V.
Figure 2 shows V from each gate plotted against the time from the release of
the ball.

top of the lower light gate.
Determine, using Figure 2, the time t taken for the ball to fall through distance h.
