Question - Calculating the Acceleration of a Mass Due to an Increased Horizontal Force

To calculate the acceleration of the mass, we will use Newton's second law of motion which states that the force acting on an object is equal to the mass of the object multiplied by its acceleration (F = ma).

Given that F1 is increased to 20 N and the acceleration 'a' is to be calculated, we can rearrange the formula to find acceleration:

a = \frac{F}{m}

However, the mass 'm' is not provided in the question. The solution cannot be determined without knowing the mass of the object. Assuming the mass was given as 'm', the acceleration 'a' of the mass would be:

a = \frac{20\ N}{m}

Without the specific value of 'm', we cannot calculate the numerical value of the acceleration 'a', but this is the formula that would be used if the mass were known.
