Answer:
increasing more mass will decrease the acceleration of the skateboarder.
Step-by-step explanation:
Newton's Second Law states whenever an unbalanced force is applied on an object, it produces an acceleration in the object in the direction of force. This acceleration is directly proportional to force by inversely proportional to mass.
where,
F = Force
a = acceleration
m = mass
If we consider force applied on the skateboarder, then the acceleration is inversely proportional to mass, only.
Therefore, increasing more mass will decrease the acceleration of the skateboarder.
