The position of a rabbit along a straight drainpipe is recorded every second: $x = 0, 0, 1, 2, 3, 2, 3, 4, 5$ m at $t = 0, 1, 2, 3, 4, 5, 6, 7, 8$ s. During which one-second interval is the rabbit moving back towards the entrance?

Options:

Answer:

Solution:

Only between $t = 4$ s and $t = 5$ s does $x$ decrease (from 3 m to 2 m), so the velocity is negative only in that interval. Option C.
