What is the mass of an object if force of -136 n can make it accelerate at -9.6 m/s^2
vampirchik [111]

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 = \frac{-136}{-9.6}

m = 14.16 grams

<em><u>Therefore the mass of an object is 14.16 grams.</u></em>
