The anser is B) 7.3 kg, you get this by multiplying times pi (3.14) and then dividing the sum.


Hope this helped!

Answer:

Mass of an object, m = 7.3 kg

Step-by-step explanation:

Given that,

Net force acting on an object, F = 8 N

Acceleration of the object, a = 1.1 m/s²

We have to find the mass of an object. It can be calculated suing second law of motion as :

F = m a


m=(F)/(a)


m=(8\ N)/(1.1\ m/s^2)

m = 7.272 kg

or

m = 7.3 kg

Hence, the mass of object is 7.3 kg
