I've answered another one of your questions with the content of how to work these out
The answer for the following problem is mentioned below.
- <em><u>Therefore the mass of an object is 14.16 grams.</u></em>
Explanation:
Force:
The push or pull on an object with mass that cause change in the velocity
It is a vector quantity.
The formula to calculate the force is:
F = m × a
Given:
Force (F) = -136 N
acceleration (a) = -9.6 m/s^2
To calculate:
mass of the object (m)
We know that,
<em>F = m × a</em>
where,
F represents the force of the object
m represents mass of an object
a is acceleration of an object
From the equation;
-136 = m × -9.6
m = 
m = 14.16 grams
<em><u>Therefore the mass of an object is 14.16 grams.</u></em>
