A stone is thrown vertically upwards. When stone is at a height half of its maximum height, its speed is `10m//s`, then maximum height attained by the stone is `(g = 10 m//s^(2))`

A

8 m

B

10 m

C

15 m

D

20 m

Text Solution

Verified by Experts

The correct Answer is:
b
`10^(2) - u^(2) - (2gh//2)`, At the maximum height `0 = u^(2) - 2gh, h = 10` m
