Question

A cyclist begins her journey from rest at t = 0 and moves in a straight line. The displacement of the cyclist throughout the journey is given in the following table. Determine:

(a) The average velocity over time

(b) The velocity-time graph

Table showing time in seconds and corresponding displacement in meters for a cyclist's journey.

Accepted Answer

The velocity of the cyclist throughout the journey is constant.

Velocity-time graph showing constant velocity of 10 m/s over time.

Answer

The velocity of the cyclist throughout the journey is uniform.

Velocity-time graph showing increasing velocity from rest to 15 m/s.

Answer

The velocity of the cyclist throughout the journey is decreasing uniformly.

Velocity-time graph showing decreasing velocity from 15 m/s to rest.

Answer

The velocity of the cyclist throughout the journey is zero.

Velocity-time graph showing zero velocity throughout the time period.
