To find the new acceleration when the force is increased, we can use Newton's second law of motion, which states that the force (F) acting on an object is equal to the mass (m) of the object multiplied by its acceleration (a): F = m * a.

Given that the initial force (F1) is 20 N and the initial acceleration (a1) is 5 m/s^2, we can use these values to calculate the initial mass (m1):

20 N = m1 * 5 m/s^2
m1 = 20 N / 5 m/s^2
m1 = 4 kg

Now, since the force is increased to 55 N, we need to find the new acceleration (a2). We can rearrange the equation to solve for a2:

55 N = m2 * a2

Since the mass (m2) remains the same, we substitute the initial mass (m1) into the equation:

55 N = 4 kg * a2

Now, to solve for a2, divide both sides of the equation by 4 kg:

a2 = 55 N / 4 kg
a2 = 13.75 m/s^2

Therefore, the new acceleration when the force is increased to 55 N is 13.75 m/s^2.

Hence, the correct answer is 13.75 kg.
