A particle has velocity v=3(t-1)(t-3) m,s-1 for 0

Question

A particle has velocity v=3(t-1)(t-3) m,s-1 for 0 <= t 4 seconds and initial displacement 2 m. Find its displacement change, total distance and average speed over these four seconds.

Accepted Answer

Displacement change $4$ m; distance $12$ m; average speed $3\ \mathrm{m\,s^{-1}}$.
