269781 A ball is projected vertically upwards with a velocity of\(25 \mathrm{~ms}^{1}\) from the bottom of a tower. A boy who is standing at the top of a tower is unable to catch the ball when it passes him in the upward direction. But the ball again reaches him after \(3 \mathrm{sec}\) when it is falling. Now theboy catches it Then theheight of the tower is \(\left(\mathrm{g}=10 \mathrm{~ms}^{2}\right)\)

269783 A stone projected vertically up from the ground reaches a height\(y\) in its path at \(t_{1}\) seconds and after further \(t_{2}\) seconds reaches the ground. The height \(y\) is equal to
