At the initial moment three points A, B and C are on a horizontal straight line at equal distances from one another. Point A beings to move vertically upward with a constant velocity v and point C vertically downward without any initial velocity but with a constant acceleration a. How should point B move vertically for all the three points to be constantly on one straight line. The points begin to move simultaneously.

Q2
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 point C vertically downward without any initial velocity at constant acceleration a. Assuming the point begin to move simultaneously, then comment on the motion of the B such that centre of mass of the system doesn't move.

Q3
A particle starting from a point A and moving with a positive constant acceleration along a straight line reaches another point B in time T. Suppose that the initial velocity of the particle is u>0 and P is the mid-point of the line AB. If the velocity of the particle at point P is v1 and if the velocity at time T2 is v2, then
