In free fall do all objects fall with the same acceleration? yes, objects fall at a rate of 9.8m/swith acceleration. For every second in free fall you must add 9.8m/s to get the acceleration of an object.
We know that gravity will always act vertically downward on the projectile. The air resistance creates a force, that is always in the opposite direction to the velocity. From Newton's second law, $F = m a$, we can see that this force will have its effect by changing the acceleration of the cannon ball.hen the projectile is fired from a height $h_0$ above the landing ground the angle for maximum range is not 45 Â° but it can be found in a similar way. Take the equation for range from a height, and differentiate.
