A student throws a baseball upwards at an angle of 60 degrees to the horizontal. The initial horizontal and vertical components are 12.5 m/s and 21.7 m/s, respectively. What position will have the greatest magnitude of vertical acceleration

All positions have constant acceleration

Explanation:

Projectiles have two velocity component; a vertical velocity and a horizontal velocity. The horizontal velocity is constant while the vertical velocity is acted upon by the force of gravity, causing a change of vertical velocity.

If the air resistance is negligible, the acceleration of a projectile would be constant and equal to the acceleration due to gravity. This means that the acceleration for a projectile is the same at every point in its trajectory.

reserve is the answer
