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 $3\sec$ when it is falling. Now theboy catches it Then theheight of the tower is $(\mathrm{g}=10{\mathrm{ms}}^2)$

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

If the person hears the sound 3 second after throwing, then the depth of water (neglect time travel for the sound and take $\mathrm{g}=10{\mathrm{ms}}^{-2}$ )
