141812 Water drops are falling from a nozzle of a shower onto the floor, from a height of \(9.8 \mathrm{~m}\). The drops fall at a regular interval of time. When the first drop strikes the floor, at that instant, the third drop begins to fall. Locate the position of second drop from the floor when the first drop strikes the floor.

141813 A balloon was moving upwards with a uniform velocity of \(10 \mathrm{~m} / \mathrm{s}\). An object of finite mass is dropped from the balloon when it was at a height of \(75 \mathrm{~m}\) from the ground level. The height of the balloon from the ground when object strikes the ground was around, is (Take, the value of \(g=10 \mathrm{~m} / \mathrm{s}^{2}\) )

141814 A ball is thrown at \(30^{\circ}\) with horizontal from the top of roof \(20 \mathrm{~m}\) high with a speed of \(13 \mathrm{~m} \cdot \mathrm{s}^{-1}\). At what distance from the throwing point will the ball, once again be at a height of \(20 \mathrm{~m}\) from the ground? \(\left(\mathrm{g}=10 \mathrm{~m} \cdot \mathrm{s}^{-2}\right)\)

141816 A hammer is dropped into a mine. Its velocities at depths \(d, 2 d\) and \(3 d\) are in the ratio
