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

Question

If a body is projected with an angle θ 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

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

Q. If a body is projected with an angle $θ$ to the horizontal, then

its velocity is always perpendicular to its acceleration

its velocity becomes zero at its maximum height

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

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

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