Question

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

A

Its velocity is always perpendicular to its acceleration

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

Answer

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

Explanation

Solution

In angular projections, the body at the highest point has velocity = u cos $\theta$ in the horizontal directions which makes zero angle with horizontal directions.
