Answer all questions in this section.
0 1 This question is about steel spheres rolling along an inclined track.
Figure 1 shows an end view of a ‘U-shaped’ track with a sphere inside the track.
The distance between the internal edges of the track is 10 mm.
Figure 1
The track is inclined at an angle θ to a horizontal bench as shown in Figure 2.
The walls of the track are transparent. A line XY is drawn on the bench at the lower
end of the track. XY is perpendicular to the track.
Figure 2
A sphere of diameter 8 mm is placed at position 1 at the raised end of the track.
When released, the sphere rolls a distance L to position 2 at the lower end of
the track.

The student makes repeated time measurements, t1 to t8, to determine the average
time T for the sphere to roll from position 1 to position 2.
Table 1 shows the data recorded by the student.

The student has identified the t6 measurement as anomalous.
Using the remaining seven readings, the student calculates that T = 3.85 s.
