Question

At the maximum height of a projectile, the velocity and acceleration are (A) parallel to each other (B) antiparallel to each other (C) perpendicular to each other (D) inclined to each other at 45°

At maximum height ; v x = v x cos θ in horizontal direction and v y =0 a x =0, a y =- g Clearly angle between them is 90°.

Q. At the maximum height of a projectile, the velocity and acceleration are

parallel to each other

antiparallel to each other

perpendicular to each other

inclined to each other at $4 5^{\circ}$

At maximum height ;
$v_{x} = v_{x} cos θ$ in horizontal direction and $v_{y} = 0$
$< b r / > a_{x} = 0, a_{y} = - g < b r / >$
Clearly angle between them is $9 0^{\circ}$ .
