A student is able to throw a ball vertically to maximum height of 40 m. The maximum distance to which the student can throw the ball in the horizontal direction :

A

`40 (2)^(1//2)m`

B

`20(2)^(1//2)m`

C

20m

D

80m

Text Solution

Verified by Experts

The correct Answer is:
D
`H_("max")=(u^(2))/(2g)=40 rArr (u^(2))/(g)=80`
`R_("max")=(u^(2))/(g)=80m`
