The displacement of a particle at time t s after leaving a fixed point O is s m. The diagram shows a displacement-time graph which models the motion of the particle. The graph consists of 4 straight line segments. The particle travels 50 m in the first 10 s, then travels at 2 m s⁻¹ for a period of 10 s. The particle then comes to rest for a period of 20 s, before returning to its starting point when t = 60. [Figure 1]
