An NCC parade is going at a uniform speed of 9 km/h under a mango tree on which a monkey is sitting at a height of 19.6 m. At any particular instant, the monkey drops a mango. A cadet will receive the mango whose distance from the tree at time of drop is:
Give g=9.8 m/s2
Give g=9.8 m/s2
- 5 m
- 10 m
- 19.8 m
- 24.5 m
The Correct Option is A
Solution and Explanation
h=ut+\(\frac{1}{2}gt^2\)
t=\(\frac{√2h}{g}\)=2 sec
x=Vt=5 m

Concepts Used:
Distance between Two Points
The distance between any two points is the length or distance of the line segment joining the points. There is only one line that is passing through two points. So, the distance between two points can be obtained by detecting the length of this line segment joining these two points. The distance between two points using the given coordinates can be obtained by applying the distance formula.
