A) 400 m
B) 20 m
C) 30 m
D) 40 m
Correct Answer: D
Solution :
Maximum height attained is given by \[{{h}_{\max }}=\frac{{{u}^{2}}}{2g}\] Given, \[u=20\text{ }m/s\] \[{{h}_{\max }}=\frac{{{(20)}^{2}}}{2\times 10}=20\,m\] For the second body also \[{{h}_{\max }}=20m\] Sum of maximum heights\[=20\text{ }m+20\text{ }m\] \[=40m\]You need to login to perform this action.
