An object falls freely from height \(h\) above the ground. It travels \(\dfrac{5}{9}h\)  of the total height in the last \(1~\text{s}.\) The height \(h\) is: \( \left (\text{use}~g =10~\text{m/s}^{2} \right )\)
1. \(5~\text{m}\) 2. \(25~\text{m}\)
3. \(45~\text{m}\) 4. \(58~\text{m}\)

A horizontal bridge is built across a river. A student standing on the bridge throws a small ball vertically upwards with a velocity \(4\) ms–1. The ball strikes the water surface after \(4\) s. The height of bridge above water surface is: 
(Take \(g=10~ \text {ms}^{-2}\) )
1. \(68\) m 2. \(56\) m
3. \(60\) m 4. \(64\) m

A small block slides down on a smooth inclined plane starting from rest at time \(t=0.\) Let \(S_n\) be the distance traveled by the block in the interval \(t=n-1\) to \(t=n.\) Then the ratio \(\dfrac{S_n}{S_{n +1}}\) is:

1. \(\dfrac{2n+1}{2n-1}\) 2. \(\dfrac{2n}{2n-1}\)
3. \(\dfrac{2n-1}{2n}\) 4. \(\dfrac{2n-1}{2n+1}\)
