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

16 m

B

10 m

C

20 m

D

40 m

Text Solution

Verified by Experts

The correct Answer is:
B
`h=((10)^(2))/(2g)=5m`

`therefore` Total height = 2h = 10 m
