If a body is projected with an angle `theta` to the horizontal, then

A

its velocity is always perpendicular to its acceleration then

B

its velocity becomes zero at its maximum height.

C

its velocity makes zero angle with the horizontal at its maximum height.

D

the body just before hitting the ground, the direction of velocity coincides with the acceleration.

Text Solution

Verified by Experts

The correct Answer is:
C

In angular projection, the body at the highest point has velocity = ` u cos theta` in the horizontal direction which makes zero angle with horizontal direction.
