Answer:
what are the options??? to choose the answer from?
Explanation:
Applying Newton's Second Law of Motion, the acceleration of the ball is 16.8 
<u>Given the following data:</u>
- Acceleration due to gravity = 9.8
To find ball's acceleration, we would apply Newton's Second Law of Motion:
First of all, we would determine the net force acting on the ball.
× 
Downward force = 4.9 N
Net force = 8.4 N
Mathematically, Newton's Second Law of Motion is given by this formula;
<em>Acceleration = 16.8 </em><em />
Therefore, the acceleration of the ball is 16.8

The center of mass isn't affected by the explosion.
To find the answer, we need to know about the trajectory of motion at zero external force.
<h3>How is the trajectory of an object changed when the net external force on it is zero?</h3>
- When there's no net external force acting on an object, its momentum doesn't change with time.
- As its momentum doesn't change, so it continues with the original trajectory.
<h3>Why doesn't the trajectory of firework change when it's exploded?</h3>
- When a firework is exploded, its internal forces are changed, but there's no external force.
- So, although the fragments follow different trajectories, but the trajectory of center of mass remains unchanged.
Thus, we can conclude that the center of mass isn't affected by the explosion.
