Question

What is the mass of an object if a net force of 8.0 N causes it to accelerate at 1.1 m/s2?

6.9 kg
7.3 kg
8.8 kg
9.1 kg

Answer 1

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 2

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
