c. Ben is correct. According to Newton's 2nd law of motion objects with more mass require more force to accelerate.
Explanation:
We can answer this question by using Newton's second law of motion, which states that the net force applied on an object is equal to the product between the mass of the object and its acceleration. Mathematically:
where
F is the net force
m is the mass of the object
a is its acceleration
From the equation, we notice that:
- The force is directly proportional to the mass of the object --> so if the mass increases, the force needed to accelerate the object will increase too
Therefore, the correct answer is
c. Ben is correct. According to Newton's 2nd law of motion objects with more mass require more force to accelerate.

<h2><u>
Collision of objects:</u></h2>
In a closed system, when two or more particles collide, the sum of momentum of two particles before and after collision will always be the same. In elastic collision, kinetic energy and momentum of a particle remains conserved. Whereas in inelastic collision, momentum remains same before and after collision but some of the particle's kinetic energy may be converted to other forms of energy.
A moving particle or object may possess kinetic energy and it depends mainly on its motion and mass. The kinetic energy is converted into potential energy and converted back to kinetic energy during collision of small particles.
