A bu llet is fired with a velocity u making an angle of `60^(@)` with the horizontal plane. The horizontal component of the velocity of the bu llet when it reaches the maximum height is:

A

u

B

0

C

`sqrt(3a)/2`

D

`mu//2`

Text Solution

Verified by Experts

The correct Answer is:
D

Here, velocity of projection fo the bullet is u
Angle of projection `theta = 60^(@)`.
At maximum height H, the horizontal component of the velocity of the bullet `=u cos theta = ucos 60^(@) = mu//2`
