Question

below are the position vs time data tables for three runners. the starting line is the reference point in each case. the positive direction is considered forward on the track.

data tables for runner a, b, and c showing time (s) and position (m) values

which runner started behind the starting line?
a none of the runners
b runner b
c runner c
d runner a

Explanation:

Step1: Check initial positions

At time \(t = 0\), Runner A has position \(0\) m, Runner B has position \(1\) m, and Runner C has position \(- 10\) m.

Step2: Determine starting - line position

The starting - line is the reference point (\(x = 0\) m). A negative position means behind the starting - line.

Answer:

C. Runner C
