The object started from rest, reached a maximum velocity of \(20 \, \mathrm{m/s}\) and then returned to rest

The object started from rest and covered a total distance of \(20 \, \mathrm{m}\) in \(4 \, \mathrm{s}\)

The object's final displacement was \(40 \, \mathrm{m}\): \(20 \, \mathrm{m}\) in the first \(2 \, \mathrm{s}\) and \(20 \, \mathrm{m}\) in the next \(2 \, \mathrm{s}\)

The object reached a displacement of \(20 \, \mathrm{m}\) in \(2 \, \mathrm{s}\) and then came back to the original point, with a final displacement of \(0 \, \mathrm{m}\)
