### ICSE X Physics Force

## A train starts from rest and moves with a constant acceleration 'a'. The guard of the train reaches the end of the platform with a speed 'v' and a passenger exactly in the middle of the train reaches the end of the platform with a speed 'u'. Determine hte speed with which a passenger seated mid-way between the guard and the passenger mentioned earlier, crossed the platform. Express it in the form of 'v'.
