Some Important Definitions of Rectilinear motion

Considering a body of mass m, radius R rotating with angular speed omega about the centre of the mass and with a velocity v of centre of mass, the most appropriate definition of rolling motion will be

Explain the meanings of rectilinear motion. Give one example

A particle starts from rest and traverses a distance l with uniform acceleration, then moves uniformly over a further distance 2l and finally comes to rest after moving a further distance 3l under uniform retardation. Assuming entire motion to be rectilinear motion the ratio of average speed over the journey to the maximum speed on its ways is
