Question: A body is thrown horizontally from the top of a tower of height 5 m.It touches the ground at a distance of 10 m from the foot of the tower.The initial velocity of the body is (g = 10 ms?2)
[EAMCET (Engg.) 2000]
Options:
A) $ 2.5ms^{1} $ B)$ 5ms^{1} $ C) $ 10ms^{1} $ D) $ 20ms^{1} $
Show Answer
Answer:
Correct Answer: C
Solution:
$ S=u\times \sqrt{\frac{2h}{g}} $
Therefore $ 10=u\sqrt{2\times \frac{5}{10}} $
Therefore $ u=10,m/s $
