Perfect! From both the animation as well as from the slope of the graph, it is clear that the maximum velocity is at \(t = 4\)s.
Let us now plot velocity as a function of time. What does the following graph tell us?

Object covered a distance of \(10 \, \mathrm{m}\) in \(2 \, \mathrm{s}\) and stayed there until \(6 \, \mathrm{s}\)

Object moved to the right until \(2 \, \mathrm{s}\), then moved up until \(6 \, \mathrm{s}\), and then moved right until \(8 \, \mathrm{s}\)

Object was at rest until \(2 \, \mathrm{s}\), then travelled at uniform velocity of \(10 \, \mathrm{m/s}\) until \(6 \, \mathrm{s}\) and then returned to rest

Object attained a speed of \(10 \, \mathrm{m/s}\) after \(2 \, \mathrm{s}\), and reversed direction at \(6 \, \mathrm{s}\) and returned to rest
