Answer:
Force = 400 Newton
Explanation:
Given the following data;
Mass = 100 kg
Acceleration = 4m/s²
Newton's Second Law of Motion states that the acceleration of a physical object is directly proportional to the net force acting on the physical object and inversely proportional to its mass.
Mathematically, it is given by the formula;
Hence, to find the force needed, we would use the above formula.
Substituting into the formula, we have;
Force = 100 * 4
Force = 400 Newton
