2. A ball is projected with a horizontal velocity of 'I .1 ms" from pointA at the edge ofa table, as shown in Fig.1.2. table horizontal ground Fig.1.2 (a) The ball lands on horizontal ground at point B which is a distance of 0.43m from the base ofthe table. Air resistance is negligible. (0 Calculate the time taken For the ball to fall from A to B. (ii) Use your answer in (i) to determine the height of the table. H5 Physics u) The ball leaves the table at time t= O. For the motion of the ball between A and B, sketch graphs on Fig.1.3 to show the variation with time t of 1. the acceleration a of the ball, 2. the vertical component 5', of the displacement of the ball from A. Numerical values are not required. Fig.1.: (1:) A ball of greater mass is projected from the table with the same velocity as the ball in (a). Air resistance is still negligible. State and explain the effect, if any, of the increased mass on the time taken for the ball to Fall to the ground
