A stone is dropped into water from a bridge 44.1 m above the water. Another stone is thrown
vertically downwards 1 s later. Both strike the water simultaneously. What was the initial speed of the second stone?
( a) 
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
A
Let the time taken by 1st stone to reach water surface be t .
Both the stones strike the water simultaneously but stone 2 is thrown ls later which means it takes is less as compared to stone 1 to cover the same distance.
Therefore, the time taken by the second stone, 
Since acceleration is constant,
