Explanation :
It is given that,
Net force acting on an object, F = 8N
Acceleration of the object, \(a=1.1\ m/s^2\)
We can find the mass of an object using second law.
According to Newton's second law of motion :
F = m a
\(m=\dfrac{F}{a}\)
\(m=\dfrac{8\ N}{1.1\ m/s^2}\)
m = 7.27 kg
So, the mass of an object is 7.27 kg
Hence, this is the required solution.
