b
7.25 kg
c
21.10 kg
d
5.65 kg

To find the new acceleration, you can use the formula:

F = m * a

Where F is the force applied, m is the mass of the object, and a is the acceleration.

In the given scenario, the initial force is 20 N and the initial acceleration is 5 m/s^2. We can calculate the mass by rearranging the formula:

m = F / a

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

Now, if the force is increased to 55 N, we can calculate the new acceleration using the same formula:

a = F / m
a = 55 N / 4 kg
a = 13.75 m/s^2

So, the new acceleration is 13.75 m/s^2.

Therefore, the correct answer is a) 13.75 kg.
