A body is projected with a speed (u) at an angle to the horizontal to have maximum range. What is its velocity at the highest point ?

A

zero

B

`u sqrt(2)`

C

`u`

D

`(u)/(sqrt(2))`

Text Solution

Verified by Experts

The correct Answer is:
D
For maximum range, `theta=45^(@)`
At the highest point, `v=ucos theta=(u)/(sqrt(2))`
