In the Q.23, the maximum height attained by the arrow is:-

A

25m

B

40m

C

31.25m

D

12.5m

Text Solution

Verified by Experts

The correct Answer is:
C
`H=(1)/(2)"gt"^(2)=(1)/(2)xx10xx[(5)/(2)]^(2)=31.25m`
[time for downward journey `=(T)/(2)=(5)/(2)`]
In this time it will fall a distance equal to maximum height.
