At the initial moment three points A ,B and C are on a horizontal straight line at equal distances from one another.Point A begins to move vertically upward with constant velocity v and. C vertically downward without any initial velocity at constant acceleration a .Assuming the points begin to move simultaneously , then for all the points to be constantly on one straight line ,the point B moves with :1. Acceleration a by 2 An initial velocity v/2both upwards2. Retardation a / 2 and initial velocity v / 2both upwards3. Zero acceleration and initial velocity v4. Acceleration a/ 2 and initial velocity v both downwards
