    A ball is thrown in air . What are its velocity and acceleration at the highest point ?

    The angle between the direction of velocity and acceleration at the highest point of a projectile path is______ .

    Assertion In projectile motion, the angle between instanteneous velocity vector and acceleration vector can be anything between o to pi (excluding the limiting case) Reason In projectile motion, acceleration vector is always pointing vertically downwards. (Neglect air friction.)

    A: A body is thrown with a velocity u inclined to the horizontal at an angle theta (theta gt 0, 90^(@)) . At the highest point, the angle between instantaneous velocity and acceleration is zero R: At the highest point velocity of the projectile is zero.

    If theta is the angle between the velocity and acceleration of a projectile at a point of its path, its value when the projectile is at the highest point is :
