# A classical mechanics problem by Shounak Ghosh

Classical Mechanics Level 3

A car starts moving rectilinearly, first with acceleration w=5m/s^{2} (initial velocity is equal to zero), then uniformly,then finally,deaccelerating with same rate w.The total time of motion t=25s.The average velocity during the time equal to <v>=72 km/h.How long does car move uniformly?
