A ball is thrown from the top of a `60m` high tower with velocity `20sqrt(2)m//s` at `45^(@)` elevation of path at highest point. (`g=10m//s^(2)`)

A

`10m`

B

`20m`

C

`40m`

D

`200m`

Text Solution

Verified by Experts

The correct Answer is:
C
`R=(v^(2))/(a_(c))=((ucos45^(@)))/(g)=((20)^(2))/(10)=40m`
